Intracavity frequency doubling of a Nd:YVO(4) laser pumped by a wavelength-locked laser diode using a transmission-type optical filter.
We demonstrate that intracavity frequency doubling of Nd:YVO(4) 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:YVO(4) yielded stable green light of 10-mW power for an incident pumping power of 55 mW.
