High pulse energies of nanosecond-level fourth- and fifth-harmonic (4omega and 5omega) generation of a Nd:YAG laser have been obtained with a CsLiB(6)O(10) (CLBO) nonlinear crystal. 500 mJ of 4omega output with a conversion efficiency of 50% from the second-harmonic input was generated. 5omega output at 213 nm of as high as 230 mJ was obtained by sum-frequency generation of the 266- and 1064-nm beams, corresponding to a 10.4% conversion efficiency of the initial fundamental input energy. The characteristics of the CLBO crystal that permit this effective frequency conversion are discussed.
利用CsLiB(6)O(10)（CLBO）非线性晶体获得了纳秒级钕:钇铝石榴石激光器第四和第五谐波（4ω和5ω）产生的高脉冲能量。产生了500 mJ的4ω输出，其从二次谐波输入的转换效率为50%。通过266纳米和1064纳米光束的和频产生，在213纳米处获得了高达230 mJ的5ω输出，对应于初始基波输入能量10.4%的转换效率。讨论了使这种有效频率转换成为可能的CLBO晶体的特性。
