【Abstract】 CsB3O5(CBO) is a new nonlinear optical crystal.It possesses a relatively large effective nonlinear optical coefficients,a high laser damage threshold(26 GW/cm2 for 1.0 ns pulses at 1053 nm),and a wide optical transparency range(167-3400 nm).CBO crystal can be expected to generate more efficient and high power ultraviolet light by frequency conversion of Nd∶ YAG laser radiation than LiB3O5(LBO) crystals.This paper presents the progress of CBO crystal on growth,properties,as well as output of ultraviolet laser.更多还原
