Description

ABSORBING TORQUE WATER AND ORGANIC MOLECULES IN A HIGH POWER LASER ENCLOSURE BACKGROUND The invention relates to absorber material for use in a sealed enclosure containing electronic circuits and at least one high power laser. As used in the present, high power refers to the intensity-i-3 light per unit area, that is, the flow of photons per 5 unit area. A high power l is one that has a photon flux density of approximately 0. Megawatts / cpv2 or more »The introduction of optical amplifiers in S telecommunication systems has led to the use of high power pump lasers. In addition, the demand for high-speed data systems with large repeater space has resulted < £ 2 using high power signal laser. It has been discovered that the packaging of such high-power beings must be modified or modified from normal industry practice to ensure the useful life of the laser. A possible mechanism for the reduced life of the laser in the normal package is the accumulation of solid or liquid material on the intensely illuminated surfaces, such as the front face of the beam, the lenses in the beam beam or the lens. fiber and windows. Surface accumulation can occur co or follow. The mobile hydrocarbons jti t from weld flow residues, cleaning solvents, contaminants in the assembly environment, or the like are present in the sealed containers. Photoreaction can occur when a hydrocarbon encounters the flow of laser photons. The products of the reaction can form a deposit on intensely illuminated surfaces. The performance of the being will be depleted by those deposits that reflect or absorb the energy. If the deposit absorbs photons, heat accumulation can occur, causing the fusion of an active or passive surface. For the laser diode, the accumulation of heat can cause accelerated diffusion of impurifiers at or near the junction thereby destroying the junction or reducing the efficiency of the junction. It has also been found that by introducing a selected amount of oxygen into the sealed atmosphere . Packing the gas acts to lengthen the life of the being. The action of oxygen may be combined with a hydrocarbon pollutant or the products of a photoreacted hydrocarbon to prevent or remove accumulations on passive to active components in the reservoir. However, oxygen in the enclosure can form water when combined with the hydrogen present in the atmosphere of the enclosure. The hydrogen can be present as a contaminant in the gas that fills the container or can be released as a gas from the metallic walls of the gas as the temperature of the enclosure increases. It is well known that water causes electrical shorts, corrosion or electro-erosion in the electrical circuits present in the enclosure. In this way there is a need for an absorber material which will serve to bind with or absorb, and thus immobilize, the impurities and water hydrocarbons that may be present in the atmosphere of the enclosure of the being. Such an absorber must: * - be able to immobilize a wide range of hydrocarbons due to the type of hydrocarbon impurity that is generally unknown; to be able to immobilize molecules having a wide range of sizes because the water molecule has a larger dimension of approximately 3 angstroms and the organic molecules present in the enclosure may have a larger dimension of approximately M-0 angstroms; being inert on the operating temperature scale of the enclosure can be inert when it is irradiated with light from the being; be of small year because the volume of the enclosure is small, typically approximately 1 to 10 cm: a; because of its small size, be very efficient to absorb organic and water molecules? and, be free of organic material or contain only organic material that does not ",. dßj "eXabSOrbed r low _" "ndiCÍO, lß" nCOntrad "inside the laser enclosure. An effective absorber for an enclosure should typically immobilize molecules in a range of sizes from about 2.5 angstroms to about 4-0 angstroms and be able to immobilize a mass of water and organic molecules at least approximately equal to iJ £ of the absorbed mass.

DETAILED DESCRIPTION OF THE INVENTION The ability of certain compounds to immobilize organic and inorganic molecules is well known. For information related to the category of zeolite immobilizing such compounds see, "The Handbook of Molecular Sieves", Rose arie Szastak, Van Nastrand Reinhold, New York, 1992. The present invention is directed to the formulation and manufacture of a molecular trap or appropriate absorber for use in a hermetically sealed enclosure for a high power l. The absorber acts to immobilize a preselected type and size of molecule. The absorber refers to a problem discovered in packaging high-power lasers. The packaging generally accepted in the industry is one that includes an inert gas in the container. The life of high power lasers was dramatically reduced when normal packaging in the industry was done. The solution to the problem of the useful life of the laser, as discussed in the patent application of Serial No. Oß / 091,657, filed on July 14, 1993, relates to the addition of oxygen to the gaseous medium in the enclosure to avoid the photoreaction of organic impurities in the enclosure with the flow of laser photon. It was recognized that the presence of oxygen in the laser enclosure could lead to the formation of water within the enclosure, thereby causing degradation of the circuits associated with the laser apparatus. This problem was focused on a C-I-P, | .N. 0 & / Í6ß, i25, filed on December 17, 1993, of the * patent application Serial No. ñ / 091/657. In the C-I-P, an absorber was introduced into the enclosure to absorb water. Additional work has been done on the absorber formulations and novel absorbers are proposed for use in high-power laser enclosures. t¿ ~, The compounds of the group > , which can be used as a component of the absorber, have an appropriate pore size or channel to immobilize molecules that have a dimension of approximately 2. angstroms, the water dimension. The group O has a small size or channel to immobilize the larger organic molecules, such as those from the welding or epoxy group, which have dimensions of tens of angstroms »Thus a formulation that includes compounds from both group W and O provides * an absorber for molecules that vary in size from about 2.5 angstroms to about 40 angstroms. This scale covers substantially all the molecules that can be present as impurities in a laser enclosure or as a result of the construction of an operating laser. The scale of size could be extended to accommodate larger or smaller impurities if the need arises. The function of the inorganic binder in the consolidated porous absorber is to prevent crumbling or fracturing of the absorber during the assembly of the enclosure l * during installation and operation of the laser. In addition, the binder provides an absorber that is not a source of dust particles that could interfere with the proper performance of the being and the associated lenses and mirrors. The reliability requirements of the telecommunications industry are strict. The telecommunications equipment is specified to operate for extended periods in environments characterized by broad temperature and humidity ranges and by vibration and iflipact.The inorganic binder in the absorber of the invention is selected to meet the exact standards of the industry. Inorganic binders are contemplated which are dispersed through the volume of the absorber and the binders which are applied only to the surface of the absorber. A preferred dispersed binder is the silica to be hardened from a silicone resin precursor, as described in the examples. Thereafter, an effective surface binder may be a layer of ground clay on the surface of the absorber before or after the ignition or calcination step. However, a clay may also be used as a binder dispersed throughout the body of the absorber. clay mineral such as a group mineral of montmorilloni a or kaolinite, or combinations thereof may be added to the absorber bath as a fluorescent. When the absorber is calcined, this clay material will impart resistance to the absorber and will improve the matter of the absorber particles thereby reducing the accumulation of dust. As an alternative, the absorber can be formed and calcined without a clay binder. After calcination, a clay mineral or combination of minerals can be ground, for example, from a solution of mineral or clay minerals, in the intergranular pore space of the absorber. After that grinding, the absorber must be dried and calcined to remove excess water. An absorber treated in this way would be resistant and essentially free of dust. The steps described above for a clay mineral can also be applied to a selected zeolite group that can be used in place of the clay to provide a strong, cohesive, and essentially free absorber J The powder. The organic binders and organic solvents and water are added to the mixture of materials that make up the absorber bath to provide a plastic consistency of the bath to facilitate the formation by extrusion, pelletization or pressure. The shape and size of the laser enclosure is typically such that the preferred absorber shape is a flat sheet approximately 1 mm thick. Extrusion is a preferred forming method because this process is cost effective to produce large amounts of body &kerde of green absorber body material having uniform dimensions and density. However, alternative forming methods are contemplated and include sedimentation, that is, pouring or washing-off, of the absorber from, for example, a suspension on a porous ceramic substrate such as silica, or an aluminosis. icata, followed by calcination at a temperature f the scale of approximately 500 to 700 ° C during approximately 4 to 12 hours. The calcination temperature is selected to be high enough to consolidate the green body and eliminate volatile particles. However, the temperature should not be so high that it reduces the immobilization ability of the zeolite. For each absorber formulation, some calcination tests may be required to establish the optimum calcination temperature in the above-mentioned scale. This method of forming can produce a sufficiently strong and dust-free absorber for use in a laser enclosure. Figure 1 is a cut-away side illustration of an absorber positioned within a high power 10 enclosure. The high power laser 6 is fixed to the substrate 2. The electronic devices and circuits that are associated with the power supply are not shown. be and typically contained in the enclosure. The means for coupling the laser light to a receiving device or to a waveguide fiber are shown as the * waveguide fiber 4. Other coupling means such as lenses or integrated waveguide slides can be used as couplers. The light can be coupled to a receiving device or to a waveguide located inside the enclosure. As an alternative, the coupling means may allow the laser light to pass out of the enclosure through a sealed opening. The absorber of the invention is shown as a thin plate attached to the inner surface. of the hermetically sealed enclosure The absocbedar 6 can be adhesively bonded, or metallized and welded, or held in a permeable container Likewise the absorber bodies can be fixedly attached to any or all of the internal surfaces of the enclosure. typically small internal of the enclosure, a single absorber body attached to an interior surface will be Affective to immobilize organic impurities and water that may be present. The device illustrated in Figure 1 can be a high power signal laser or a high power pump for an amplifying fiber. The typical practice in the case of a pump laser is to couple the laser to a waveguide amplifying fiber by means of coupling means which conduct the light through a sealed opening in the wall of the enclosure.

A waveguide fiber is a typical coupling medium.

Figure 2 is an illustration of the parts of a high-power ßsser. The laser operating body 12 is shown to have a front face 14. The partially reflecting mirrors of the front and rear face 20 and 16, respectively, support the operation of the operation. The flow of photon through the front mirror 20 is, in general, approximately a factor of 10 times greater than the flow through the back face. The reactions, which may cause deposits on the mirror 20 or other fish components within the enclosure, take place in the flow path beginning in the mirror 20. These photoreactions are those that the absorber eliminates or limits to quantities that affect the performance of the laser.

EXAMPLE 1 A 35% by weight bath of zeolite ZSH-5, 35% by weight Hf zeolite 4A, and 20% by weight of fused silica powder were dry mixed »19% by weight of Dow Corning silicone resin was added 06- 2230 and mix dry in the bath. This amount was sufficient to produce approximately 10% by weight of silica in the finished absorber. The Dow Corning methylocellulose at approximately 6% by weight overshoot was mixed dry in the bath. The percentage by weight of base is taken as the combined weight of the components W, 0, and the inorganic binder. A percentage of super addition is calculated on the bae by weight but is not included in the - Base rate for the weight percentage calculations. An organic solvent, either isopropyl alcohol or Dupont dibasic ester, and water were added to the dry mix to produce an extrudable bath consistency. The plasticized bath was extruded into flat sheets having a thickness no greater than about 1 mm. The green body sheets were air dried at about 95 ° C for 1-5 days. An alternative drying method is the use of a jgue dielectric oven can reduce the drying time to a few minutes. The dried sheets were calcined in the air at approximately 600 ° C for about 10 hours. The resulting absorber sheets were strong and substantially free of dust.

EXAMPLE 2 jfc. Using the same mixture, plastification and extrusion process of example 1, an absorber having a composition of 30% by weight of zeolite 4A, 30% by weight of zeolite ZSM-5, 10% by weight of silica was made from silicone resin and 30% by weight of a glass frit having a melting temperature of up to 500 ° C. The green absorber body was calcined as in Example 1. A strong and substantially dust-free absorber was obtained.

EXAMPLE 3 A more preferred embodiment of the invention is the formulation, using essentially the same procedure than in Example 1, approximately 35% by weight of zeolite 4A, approximately 35% by weight of zeolite ZMS-5, approximately % by weight of Vycor ™ and approximately 10% by weight of silica from a silicone resin precursor. The bath was plasticized, extruded and calcined as in example i. He The resulting absorber had exceptional properties of Resistance and was essentially dust-free An absorber was cut out from the sheet and inserted into a high-power laser enclosure that was then filled with a gaseous medium containing> 15 -20% of oxygen and a hermetically sealed container. * In addition, a tightly sealed container was prepared as indicated above with no oxygen in the gaseous medium.The energy of the rear face was continuously monitored and monitored.

"Deposit sensitive indicator on critical surfaces of l. No indication of failure has been observed after more than 10 hours of operation. It will be noted that certain modes of the absorber are designed to immobilize water as well as organic molecules. However, the modes of the absorber are contemplated where the organic molecules are the primary objective of the absorber. These last modalities are applicable in those situations where the water is aetrolled in the construction of the enclosure and the oxygen is not required due to the efficiency of the absorber. It is apparent that absorbers designed to immobilize only water are within the scope of the invention.
