Abstract :
Combination of intra-cavity SHG and passively-Q-switching demonstrated on 473 nm quasi-four-level Nd:YAG laser. Periodically-poled MgO:SLT was inserted into the 10 mm length cavity of passively-Q-switched Cr:Nd:YAG laser. A longitudinally pumping with 4 W laser diode shows beam quality of M2 ap1. The output energy of 29 muJ and pulse duration of 3.1 ns were obtained.
