摘　　要：为改善高功率激光器激光工作物质的热效应,本文采用热键合的方法研制了Nd:YVO4/YVO4复合晶体,键合晶体的波前干涉P-V值为0.082λ(λ=0.6328μm),键合面对波前的影响很小。它在LD端面连续泵浦条件下,从泵浦光到基频光的转换效率可达60%,特别当泵浦功率比较大时,键合晶体的输出功率比单块晶体有较大的提高。In order to improve the thermal effect of lasing crystal, a composite crystal of Nd： YVO4/YVO4 is made using the diffusion bonding method. The P-V value of wave front distortion of the composite crystal is 0. 082λ （ A = 0. 6328 μm）. It indicates that the interface has little effect on the wave front distortion. When the composite crystal is end pumped by the laser diode, the transform efficiency from the pump power to the output power is about 60%, which is much higher than the single crystal especially when the pump power is high.
