A kind of double disk gain crystal double bonds of the invention close the thin-sheet laser of YAG direct cooling, are by two thin slices
Yb:YAG crystal, two pumping pumping systems, a set of once-through cooling system are constituted, concrete operating principle are as follows:
By aspherical resonant cavity 9, (aspherical resonant cavity uses the light pumped from left pumping system in left pumping system
The aspherical parabolic mirror in pumping system), turnover cylindrical prism 12, transfer cylinder rib 13 turning mirror focus on left increasing
On the right bonded crystals of beneficial crystal, the light pumped from right pumping system passes through aspherical parabolic mirror 11, turnover cylindrical prism
12, the turning mirror of turnover cylindrical prism 13 focuses on the left bonded crystals of right gain crystal.The gain crystal of the laser is
Double bonded crystals (including left bonded layer 3,6, right bonded layer 5,8 and middle layer 4,7), by taking left gain crystal as an example, left bonded layer
It is to effectively inhibit to be excited spontaneous radiation, right bonded layer is to eliminate because of direct cooling bring optical distortion.
Such as the laser crystal that Fig. 5 is single left and right bonding, middle layer is to adulterate the YAG lasing light emitter of Yb；For left increasing
Beneficial crystal, left surface (left surface here refers to the face not combined with middle layer) plating 1030um anti-reflection film of left bonded layer 3
It is then plated with the right surface (right surface here refers to the face not combined with middle layer) of the anti-reflection film of 940um, right bonded layer 5
The anti-reflection film of 1030um and the reflectance coating of 940um.Right gain crystal is then just opposite: the increasing of left 6 surface of bonded layer plating 1030um
The reflectance coating of permeable membrane and 940um, the anti-reflection film of the plating of right surface the 1030um anti-reflection film and 940um of right bonded layer 8.
It should be understood that " left side " and " right side " in the present embodiment is in contrast, to be not meant to limit specific position,
And it is intended to indicate that the relative position of bonded layer and middle layer and the relative position of two gain crystal.

Face resonant cavity mirror 10 is then the spherical mirror designed by the curvature of matching 9.
It is injected into the crystal of left and right double bond conjunction by the semiconductor laser of left and right pumping, (this is humorous by resonant cavity for crystal
Shake chamber centre be cooling deionized water) afterwards issue 1030um laser.
The pumping system of laser of the present invention is semiconductor laser pumping source by one with optical fiber, an aspherical parabolic
Face is reflected focus lamp, 4 90 degree of turnover cylindrical prisms, a 180 degree turnover cylindrical prism and a plane receipts light end mirror and is constituted.
The reflection for carrying out 90 degree to pump light by 4 deflecting prisms, then focuses on thin-disc laser for the light of reversion by aspherical
On the crystal of device, to realize repeatedly to the pump absorption of pump light.
The laser of the present embodiment improves gain crystal to the absorption efficiency of pump light using the mode of two-stroke pumping；
Using double bond conjunction, the gain crystal structure of two-slices, optical distortion caused by compensating for because of fuel factor improves defeated the laser
The beam quality of light, while the left button zoarium of double bond conjunction effectively inhibits the spontaneous radiation of being excited of crystal, right button zoarium is then protected
The water flow for having demonstrate,proved crystal is directly cooling；The direct cooling that the laser uses is rear bonding body and the right increasing by left gain crystal
The left button of beneficial crystal is fit, and the thermal efficiency of this mode bicrystal can be reduced greatly；The invention uses aspherical and spherical surface
Concave-concave chamber composition, can greatly reduce optical aberration bring wavefront distortion improve output light beam quality；The laser
Double stimulated radiations of the mode that device is pumped using a kind of two-slices, two-slices superposition can greatly improve the defeated of output light
