摘要

With tin diselenide (SnSe2) film as a saturable absorber (SA),the passively Q-switched self-frequency doubling (SFD) lasers were realized in Nd3+∶ReCa4O(BO3)3 (Re =Y,Gd) crystals.For Nd∶YCa4O(BO3)3 crystal,the maximum average output power at 532 nm was 19.6 mW,and the corresponding pulse repetition frequency,pulse duration,single pulse energy,and peak power were 17.6 kHz,91.9 ns,1.1 μJ,and 12.1 W,respectively.For Nd∶ GdCa4O(BO3)3 crystal,these values were 14.5 mW,22.1 kHz,48.7 ns,0.66 μJ,and 13.5 W.
