Adopting the above structure, the utility model can realize precise adjustment of a relative position of the frequency doubling crystal or the optical component, and the best frequency doubling efficiency can be achieved, the structure has the advantages of low cost and simple manufacture, wherein partial components are adjustable.
Description
Technical scheme the utility model relates to field of lasers, relates in particular to a kind of micro-piece type laser cavity that adopts average cavity configuration.
Background technology
The micro-slice laser cavity configuration has been widely used in the semiconductor pumped laser, be that its gain medium Nd:YV04 constitutes one with the parallel plain film of frequency-doubling crystal KTP by the gummed bonding, form extra small size microchip laser chamber and be applied in the semiconductor pumped green (light) laser.Wherein adopt directly to cut into small pieces behind the gummed of large stretch of gain medium Nd:YV04 and frequency-doubling crystal KTP and use, can reduce cost greatly, can be directly used in end pumping simultaneously, only need simple mobile pumping point position, can obtain to export.
Yet this structure is easy to processing and fabricating for accepting the big frequency-doubling crystal KTP in angle, but for accepting angle especially little frequency-doubling crystal BBO, BiBO, control machining angle precision is but very difficult, is difficult to produce micro-slice laser.In addition, when longer, be difficult for being made into the logical little device of optical cross-section,, then can improve the cost that microplate is made if add the size of the logical light face of megacryst as if micro sheet structure length.
Utility model content the purpose of this utility model is to provide a kind of employing average cavity configuration, the micro-piece type laser cavity that optical element can fine adjustment.
The utility model realizes that the technical scheme that above purpose adopts is: micro-piece type laser cavity comprises etalon support, gain medium and a frequency-doubling crystal, before and after laser cavity, be respectively equipped with ante-chamber sheet and back cavity sheet, wherein gain medium is fixed on the etalon support, frequency-doubling crystal or optical element are fixed on the micro-adjusting mechanism, and micro-adjusting mechanism is fixed on the etalon support.
Micro-adjusting mechanism is concavo-convex ball-joint support.
When the optical element before the back cavity sheet is angle of wedge sheet, the inclined-plane of the parallel angle of wedge of back cavity sheet.
Chamber, front and back sheet bonding a slice or the above optical material of a slice form chamber, compound front and back sheet.
The utility model adopts above structure, can realize the fine adjustment of frequency-doubling crystal or optical element relative position is reached best shg efficiency; When adopting angle of wedge sheet, can produce laser oscillation cavity; Adopt chamber, compound front and back sheet, select the control criterion tool support and the Compound Cavity sheet coefficient of expansion, whole laser cavity component temperature is compensated, laser cavity varies with temperature less or constant.This infrastructure cost is low, and the subelement scalable is made simple.
