Abstract

There has been much recent interest in the development and applications of diode-laser-pumped solid-state lasers. Efficient frequency doubling of these lasers requires some method to increase the intensity in the doubling crystal over that available from the diode pump, since the diode pump intensities are relatively small. Diode- pumped solid-state lasers have been Q-switched or mode-locked to produce high-peak-power outputs that can be efficiently frequency doubled. Approaches to cw second harmonic generation have concentrated on intracavity frequency doubling, where advantage is taken of the high circulating intensity present inside the laser resonator.
