Abstract

A stable low-threshold self-Q-switched diode-pumped 946-nm Nd3+,Cr4+:YAG microchip laser operating in single frequency and fundamental transverse mode is reported. The output characteristics of the microchip laser were investigated under cw and pulsed pumping. By combination of the infrared microchip and an external frequency doubler, 473-nm pulses with a conversion efficiency of 18% were achieved.
