摘要

我们报道了利用LiIO3和KTP晶体的组合，将1.32微米Nd:YAG激光发射效率提高了三倍。在KTP中，0.44微米的辐射发生在纯非临界相匹配条件下，温度稍高。在4 mm长的KTP晶体中，三次谐波产生相对于二次谐波能量的转换效率约为60%。给出了转换过程的温度和角度特性。

Highly efficient third harmonic generation of 1.32-μm radiation of a Nd:YAG laser in KTP

We report highly efficient cascade tripling of 1.32 micrometers Nd:YAG laser emission using combination of LiIO3 and KTP crystals. The generation of 0.44 micrometers radiation in KTP has been shown to occur at the purely noncritical phase-matching condition at slightly elevated temperature. Conversion efficiency of third harmonic generation in relation to second harmonic energy was approximately 60% in 4 mm long KTP crystal. The temperature and angular characteristics of conversion are presented.
