Abstract

Second harmonic generation (SHG) in a nonlinear uniaxial crystal is theoretically studied. The main attention is paid to the estimation of the wave detuning effect on the SHG efficiency. The results presented confirm a strong dependence of the optimal value of wave detuning on the laser radiation power and a way of radiation focusing into a nonlinear crystal. A quite rapid algorithm is suggested for the numerical solution of the problem of wave detuning optimization. The applicability of this algorithm to the analysis of highly efficient SHG is shown, including situations where the nonlinear conversion efficiency attains its maximum.

有效二次谐波产生期间的波失谐优化

摘要

理论上研究了非线性单轴晶体中的二次谐波(SHG)。主要关注波失谐对SHG效率的影响。提出的结果证实了波失谐的最佳值对激光辐射功率的强烈依赖性以及将辐射聚焦为非线性晶体的方式。对于波动失谐优化问题的数值解,提出了一种相当快速的算法。显示了该算法在高效SHG分析中的适用性,包括非线性转换效率达到最大值的情况。
