摘要
利用两块β－ＢａＢ２ Ｏ４（ＢＢＯ）晶体有效实现对平均功率为４００ ｍ Ｗ 左右、重复频率为１０ ｋＨｚ的准连续调谐钛宝石激光的倍频，获得了波长范围为３６０～４７６ ｎｍ 的调谐紫外及可见光源；利用和频效应获得了调谐范围为２４０～２６０ ｎｍ
Efficient frequency doubling has been realized by using two BBO nonlinear crystals with a quasi continuous wave tunable Ti:sapphire laser whose repetition rate is 10 kHz. Tunable ultraviolet and visible light within the range of 360~476 nm is obtained. Third harmonic radiation ranging from 240~260 nm has also been obtained by frequency tripling.
