Abstract

We demonstrate that intracavity frequency doubling of Nd:YVO4 pumped by a laser diode can be stabilized by use of a wavelength-locking system of the laser diode with a transmission-type optical filter in a confocal optical configuration. The wavelength locking of the laser diode to the peak wavelength of the absorption spectrum of Nd:YVO4 yielded stable green light of 10-mW power for an incident pumping power of 55 mW.
