Abstract
A laser system includes a laser resonator cavity having a resonant axis and an Er:glass, Er:YAG, or other lasing element with an output of from about 1.4 to about 1.65 micrometers within the laser resonator cavity. A flash lamp optically pumps the lasing element to emit light. A Q-switch crystal lies along the resonant axis within the laser resonator cavity. The Q-switch crystal is formed of a host material having a concentration of U.sup.2+ ions therein, so as to be a saturable absorber of the light emitted by the lasing element. The Q-switch crystal is preferably a U.sup.2+ -doped fluoride such as U:CaF.sub.2, U:SrF.sub.2, or U:BaF.sub.2.
