摘要
对LD端面泵浦Nd∶KGW激光器的热效应进行了分析.求解热传导方程得出了Nd∶KGW晶体的温度分布和端面形变,进而计算出了热焦距随泵浦功率的变化曲线,并通过实验对其正确性进行了验证.采用凹-平腔,在不同透过率的输出镜下,对Nd∶KGW晶体的1 064 nm连续激光输出特性进行了研究.
The thermal effect of diode end-pumped Nd ： KGW laser is studied. The temperature fields distribution in Nd ： KGW crystal and end-face deformation were obtained by heat exchange equation. And the figures of the thermal focal length dependence on pump power were calculated which are validated by experimental results. The output characteristics of Nd ： KGW 1 064 nm laser in concave-plane cavity were studied using output mirrors with different transmission.
