Diode-pumped intracavity frequency-doubled passively Q-switched Nd lasers

Abstract

The analytical model of intracavity frequency doubled end pumped laser has ben worked out and applied to optimize the major components of such laser. The experiments of cw and passively Q-switched intracavity doubled Nd lasers were carried out. About 1 W of averaged green power, with pulse energy of 150 (mu) J, pulse duration of 40 ns were achieved for 10 W fiber coupled pumping diode. The directions of optimization of such lasers were formulated.
