摘要
用５ｍｍ的ＫＴＰ（ＫＴｉＯＰＯ４）和ＢＢＯ（β－ＢａＢ２Ｏ４）非线性晶体，对皮秒的ＣＰＭ，Ｎｄ∶ＹＡＧ脉冲激光的腔外倍频效应进行研究，获得倍频能量转换效率分别为４２％和３２％，证明ＫＴＰ倍频效率高于ＢＢＯ，结果与理论分析相符．
The extracavity second harmonic generation (SHG) of nonlinear crystals KTP and BBO on picosecond CPM, Nd: YAG pulsed laser are studied experimentally. For a KTP or BBO crystal with a length of 5 turn,a 42% or 32% efficiency of frequency-doubled energy conversion can be obtained respectively. The frequency doubling efficiency of KTP is demonstrated experimentally to be higher than that of BBO, a result coinciding with that from theoretical analysis.
