Abstract
This invention discloses a polygonal hot bonded compound laser medium and its making method. The polygonal hot bonded compound laser medium is seamless integrity composed of two or several blocks of medium, the medium is chosen from laser crystal, such as Nd:YAG, Cr: YAG, Nd:GGG, Yd:GGG, the laser glass, such as Nd glass; flatten and polish the connecting surface of the two or several same or different mediums, carry out optical agglutination and press tightly, increase the temperature slowly to the proper temperature, maintain the temperature for a while, and decrease the temperature to room temperature, and realize the permanent bonding between the mediums. Through the improvement of the performance of the laser medium, it can meet the demand of the fast development of highly efficient laser.
Description
Technical field
The present invention relates to optical field, specifically a kind of preparation method of polygonal heat bonding composite laser medium.
Technical background
Working-laser material is the core part of laser.Operation material is meant the material that can produce stimulated radiation.
Traditional working-laser material element is the single integral body of same monocrystalline or glass, in this monocrystalline or glass inside without any processing equipment, optics, chemical process and processing, define this and be single working-laser material, as Nd:YAG rod, the thin dish of Nd:YAG, Nd:YAG lath, neodymium glass etc.
Along with the development of superpower laser, this operation material is dispelled the heat, the restriction of stress, size etc., has limited laser power and beam quality.
Summary of the invention
The present invention has designed novel working-laser material, this working-laser material no longer is single operation material, but pass through the operation material that thermal bonding technology is bonded together by a plurality of (comprising one) single operation material and other crystal or glass, be called the recombination laser working media.
Technical scheme
Polygonal heat bonding composite laser medium, be two or polylith medium constitute in conjunction with whole, it is one of following that described medium is selected from:
(1), the laser crystal that mixes, as Nd:YAG, Cr:YAG, Nd:GGG, Yb:GGG;
(2), unadulterated crystal, as YAG, GGG, GdVO
4, YVO
4, KTP;
(3), the doping laser glass, as neodymium glass;
(4), doped-glass not, as ordinary optical glass.
Described composite laser medium is characterized in that described two or polylith medium are media of the same race, or medium not of the same race.
The preparation method of polygonal heat bonding composite laser medium, it is characterized in that two or polylith medium identical or inequality, its faying face is processed smooth bright and clean, carry out the optics gummed, and compress, slowly be warmed up to uniform temperature again after, constant temperature keeps certain hour again, slowly reduce to room temperature again, realize the permanent bonding between the medium.
When two or polylith medium were crystal with matrix, then the bonding plane was same crystal orientation; When two or polylith medium are non-crystal with matrix, then to determine the orientation of different crystal respectively according to the needs of function.
The fineness on the bonding plane of two or polylith medium is more than the optics secondary, until the ultra-smooth plane; Flatness is zero aperture, i.e. N=0.
The pressure that compresses two or polylith medium is at 10 newton/cm
2～1000 newton/cm
2Between, thermostat temperature is lower than 200～300 ℃ of fusing points minimum in two or the polylith medium.
Inventive principle
Two or polylith medium by certain orientation, after being worked into certain fineness, flatness, after room temperature realizes the optics gummed, apply certain pressure to sample, heat up to sample by certain speed, after temperature is elevated to certain value, constant temperature a period of time cools to room temperature by certain speed again, thereby under need not the situation of any binding agent, by flowing of molecule, realize the permanent bonding of medium.Complex media behind the bonding is the entity of even transition, and the optical transmittance of the entity behind the bonding is rationally discussed to see through and conformed to, and the medium behind the bonding can stand common optics, machining.
Advantage of the present invention:
A, help the cooling of complex media element.
If medium is the laser active ionic medium that do not mix, then pump light is not produced absorption, can be used as heat sink heat radiation.
B, help the design of clamping structure and cooling, can not influence the gain of medium because of these structures.
C, because the edge medium generally all not have to absorb to laser and pump light, and therefore, the temperature rise of edge medium is little, and the medium edge distortion is little, helps the plated film on the protective medium, the raising beam quality.
D, can with a complex media realize respectively laser frequency multiplication, transfer functions such as Q or waveguide operation.Also can make this complex media have one or more function simultaneously.
