比较了三种方案(“角度失谐”、“偏振失配”和“偏振旁路”)，实现了1μm激光辐射的高效三倍频。根据对输入强度、偏振角和失配角的敏感度，考察了它们的总体特性。“偏振失配”方案有利于用KdP晶体将当前高功率1μm掺钕玻璃激光辐射提高两倍，而对于未来的系统，“偏振旁路”方案可能是最优的。所有方案都允许将一些整形脉冲增加三倍，而不会显著降低效率。回顾了KDP中的三倍频理论。
A comparison is made of three schemes ("angle-detuned," "polarization-mismatch," and "polarization-bypass") permitting high efficiency frequency tripling of 1 μm laser radiation. The overall characteristics of each are examined in terms of sensitivity to input intensity, polarization angles, and mismatch angles. The "polarization-mismatch" scheme is favored for tripling current high-power 1 μm Nd:glass laser radiation with KDP crystals, while for future systems the "polarization-bypass" scheme may be optimum. All schemes permit the tripling of some shaped pulses without substantial degradation in efficiency. The theory of tripling in KDP is reviewed.
