PASSIVELY Q-SWITCHED, FREQUENCY DOUBLED, ND:YAG LASER, WITH CR~(4+):YAG SATURABLE ABSORBER

摘要

The output characteristics of a continuous-wave, lamp pumped, Nd:.YAG laser, passively Q-switched by Cr~(4+):YAG are reported. In order to control the small-signal transmission of the passive Q-switch, a new method, which made use of a small diode laser placed out of the resonator, is described theoretically and proved experimentally. Folded resonator was used in order to obtain intracavity second harmonic generation in passive Q-switch mode.
