It includes semiconductor laser, focusing lens, wedge laser crystal, wedge accent Q crystal, semiconductor laser output beam direction from the left hand right side is in proper order focusing lens, ante -chamber rete, wedge laser crystal, wedge transfer Q crystal, back cavity rete. Laser crystal with transfer the Q crystal to have the same angle of wedge. Laser crystal's incident surface and the emitting face of transferring the Q crystal have plated ante -chamber rete and back cavity rete respectively. Can make laser crystal length and the continous transform that transfers the Q crystal length through the horizontal position that removes pumping light, go back the accessible and change the change that the chamber length was realized to laser crystal and the horizontal position of transferring Q crystal angle of wedge face.
Description
Technical field
The utility model relates to laser device field, particularly relates to the micro-slice laser that a kind of crystal length is adjustable.
Background technology
Micro-slice laser has that volume is little, compact conformation, stable, life-span length, all solid stateization, conversion efficiency are high and the advantages such as cheap easy batch production.The chamber of micro-slice laser is long shorter, easily realizes good beam quality, and the single longitudinal mode single frequency laser that light intensity brightness is large exports, and makes it have important value in laser radar, laser ranging, laser sensing, laser medicine and the field such as optical storage, nonlinear optics.
But the laser crystal that at present micro-slice laser uses is all generally regular length, due to microplate Theoretical Design and actual export between there is difference, the verification experimental verification being directed to this is comparatively loaded down with trivial details, therefore proposes this patent.It is workable that it is tested, and can continuously change the size of microplate very easily, reach the Performance optimization of microplate.
Summary of the invention
This patent overcomes the deficiencies in the prior art, provide a kind of crystal length adjustable and optical cement can be adopted, micro-slice laser that in-depth optical cement, gluing method are bonded to one.
To achieve these goals, this patent adopts following technical scheme:
The micro-slice laser that crystal length is adjustable, comprises semiconductor laser, condenser lens, wedge shape laser crystal, wedge shape adjusting Q crystal; Semiconductor laser output beams direction is described condenser lens, ante-chamber rete, wedge shape laser crystal, wedge shape adjusting Q crystal, back cavity rete from left to right successively, and described laser crystal and adjusting Q crystal have the identical angle of wedge.
The plane of incidence of described wedge shape laser crystal is coated with the anti-reflection film of semiconductor laser output wavelength and the high-reflecting film of laser crystal Output of laser wavelength, as the ante-chamber rete of resonant cavity.The exit facet of wedge shape adjusting Q crystal is coated with the high-reflecting film of semiconductor laser output wavelength and the anti-reflection film of adjusting Q crystal Output of laser wavelength, as the back cavity rete of resonant cavity.Adopt between described wedge shape laser crystal and wedge shape adjusting Q crystal optical cement, in-depth optical cement be bonded to one.
Can make continuously changing of laser crystal length and adjusting Q crystal length by the lateral attitude of mobile pump light, the lateral attitude also by changing laser crystal and adjusting Q crystal angle of wedge face realizes the long change in chamber.
Profitable fruit of the present utility model is that the test of this kind of micro-slice laser is workable, can continuously change the size of microplate very easily, make the Performance optimization of microplate.And greatly reduce the time cost of materials processing and test, and as long as time processing just can determine the performance of a series products among a small circle, also can the optimal anchor direction of guide product.
