Ultraviolet generation tunable to 0.185 μm in CsLiB↓(6)O↓(10)

摘要

CsLiB↓(6)O↓(10) has been found to be phase matchable for type-1 sum frequency generation to a minimum of 0.185μm by mixing the fifth harmonic of a Nd:YAG laser at 1.0642 μm and the output of a KTP parametric oscillator pumped by the second harmonic of the same Nd:YAG laser at 20.0 ℃. The improved Sellmmeier equations and the thermo-optic constants of this crystal are reported. # 1997 Optical Society of America
