摘要
利用新的解析热分析方法得出了矩形截面非线性晶体在TEM00模式辐射下产生的温度场计算表达式,分析了影响非线性晶体内部温度场分布的各种因素,对比分析了矩形截面和近似圆形截面时所存在的差异及产生的原因.得出的结论为后续研究由于温升引起的位相失配等系列问题提供了理论基础,同时对于提高DPSSL系统输出功率具有指导意义.
The general solution of crystal under TEM00 with rectangular section interior temperature field distribution was obtained by a new semi-analytical thermal analysis method. Subsequently some relevant parameters, which would influence temperature field distribution, were analyzed. And discrepancy between the rectangular section crystal and the circular section crystal was compared. Research results will be theoretically established for further research, such as phase mismatching induced by non-uniform temperature raise, and play instructive effect at improvement of DPSSL's output power.
