摘　　要：With tin diselenide(SnSe2)film as a saturable absorber(SA),the passively Q-switched self-frequency doubling(SFD)lasers were realized in Nd^3+: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,1.1μJ,and 12.1 W,respectively.For Nd:GdCa4 O(BO3)3 crystal,these values were 14.5 mW,22.1 kHz,48.7 ns,0.66μJ,and 13.5 W.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.
