Abstract
The invention discloses a water-cooled packaging structure of an optical fiber beam combiner. The water-cooled packaging structure comprises a sealing box body, a beam combiner optical fiber and a substrate. An optical fiber inlet and an optical fiber outlet are formed in the opposite side faces of the sealing box body. The beam combiner optical fiber is fixed to the substrate through optical cement. The substrate is then fixed in the sealing box body through optical cement. A liquid inlet and a liquid outlet are further formed in the sealing box body and connected with a water circulating device. The sintered portion of the beam combiner optical fiber is soaked in circulated water. By means of the water-cooled packaging structure, energy can be prevented from being accumulated on the beam combiner, it is ensured that the beam combiner works under a good working state, and then work stability of the beam combiner is improved.
Description
Technical field
The present invention relates to the encapsulation of optical-fiber bundling device, relate in particular to a kind of water-cooled encapsulating structure of large-power optical fiber bundling device.
Background technology
Along with developing rapidly and maturation of Fiber laser technology, the characteristics and advantages of fiber laser is familiar with by people gradually, fiber laser has obtained increasingly extensive application in fields such as national defence, industrial processes, medical treatment, the market demand and application are significantly increasing year by year, and this certainly will produce the heavy demand to optical-fiber bundling device.
Optical-fiber bundling device is one of core component of high power fiber laser, it is the most effective pumping coupler part at present, it can be coupled into the energy efficient of multiple laser instruments an Optical Fiber Transmission, it uses power generally in tens watts, a few hectowatt, kilowatt magnitude even, high-power work like this, the reliability of bundling device is proposed to high standard requirement, for example its long-term working stability, heat dissipation design reliability etc.
Powerful bundling device must carry out cooling while use, the cooling means that industry generally adopts is at present external refrigeration method, fiber section by bundling device is isolated from the outside, the heat that optical fiber produces conducts to the covering box body of bundling device, then box body is dispelled the heat, this method heat conduction efficiency is not high, has the poor problem of radiating effect.There is 70% left and right can become heat exhaustion according to the power of statistics fiber laser input and fall, if these heats do not dissipate the high workload power that can directly affect device as early as possible, even whole fiber laser can be burnt out.Therefore the bundling device encapsulating structure of, developing a kind of high efficiency and heat radiation is technical matters urgently to be resolved hurrily in the industry.
Summary of the invention
The present invention proposes a kind of water-cooled encapsulating structure of novel optical-fiber bundling device, and this structure can prevent the gathering of bundling device heat, and ensures that bundling device works under a good working order, thereby increases the job stability of bundling device.
The water-cooled encapsulating structure of the optical-fiber bundling device that the present invention proposes comprises: sealing box body, bundling device optical fiber and substrate, described box body opposite flank is provided with optical fiber and imports and exports, bundling device optical fiber is fixed on described substrate with optical cement, described substrate is fixed in described sealing box body with optical cement again, on described sealing box body, be also provided with liquid entrance and be connected with water circle device respectively, the optical fiber of described bundling device fuses part and is immersed in recirculated water.
In one embodiment, described substrate adopts transparency carrier, and described sealing box body adopts transparent box body.
Described water circle device can adopt normal-temperature water, or chilled water circulating device.
The present invention is simple in structure, and heating part directly contacts with recirculated water, and heat can be recycled water in time, take away fully, makes the inside of bundling device not assemble heat-collecting capacity, has greatly improved high workload power and the reliability of bundling device.
Brief description of the drawings
Below in conjunction with drawings and Examples, the present invention is described in detail, wherein:
Fig. 1 is structure cut-open view of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Fig. 1 and Fig. 2 show a specific embodiment of the present invention.The water-cooled encapsulating structure of the optical-fiber bundling device that the present invention proposes comprises: bundling device optical fiber 1, substrate 2 and sealing box body 3.Sealing box body opposite flank is provided with optical fiber and imports and exports, and bundling device optical fiber 1 use optical cement is fixed on substrate 2, and substrate is fixed in sealing box body 1 with optical cement again.On sealing box body, be also provided with liquid entrance and be connected with water circle device respectively, the optical fiber of bundling device fuses part and is immersed in recirculated water.
In one embodiment of the invention, made (6+1) × 1 type bundling device, pumping input fibre is 200/220 0.22NA, and signal input and output signal fibre is 30/600 0.06/0.46NA.When encapsulation, bundling device optical fiber 1 use optical cement is fixed on to the upper surface of substrate 2, substrate 2 use optical cements are fixed on the middle, bottom of transparent cavity, the cavity wall of sealing box body is passed at the two ends of optical fiber by aperture, clean recirculated water injects from import 4, forms stable circulation from exporting 5 outflows.
Substrate 2 and sealing box body 3 can adopt transparent material.
External water circle device can adopt normal-temperature water circulating device, or chilled water circulating device.
The test result of above-mentioned method for packing under logical 20 ° of cold water is:
6 pumping ends access respectively 100W 915nm laser instrument, and output power 588W(pumping efficiency mean value is 98%).
Observe bundling device cone district with temperature measurer, have no heat generating spot, continuous working 48h, bundling device heat distribution is stable.
The present invention is applicable to the encapsulation of all kinds bundling device such as N × 1, (N+1) × 1, the heat that is not coupled into the light conversion of output optical fibre can be taken away by water rapidly fully, core-fiber section temperature of bundling device can not raise, therefore, use the present invention propose bundling device encapsulating structure possess long-term working stability good, can tolerate the feature that power is high.
Below the present invention is specifically described, but those skilled in the art can make numerous variations or variation to these embodiments, within these changes and variation should fall into the scope of protection of the invention in conjunction with the embodiments.
