Abstract
We carried out the operation of an intracavity frequency-doubled self-Q-switched Nd,Cr:YAG/KNbO3 946/473nm microchip laser pumped by a Ti:sapphire laser. The overall cavity length was about 4 mm. The maximum average blue power of 12 mW was achieved with a repetition rate of 13 kHz at an absorbed pump power of 545 mW. The pulses of 473 nm laser had duration of 7ns and peak power of 132 W at this pump level. The conversion efficiency was 2.2 % with respect to absorbed pump power of 808 nm laser.
