Method and device to avoid optical damage of an intracavity optic

摘要

A laser oscillator has a resonator including a high reflector, an output coupler and a gain medium is positioned in the resonator. A diode pump source is provided, the pump source and gain medium create a lensing effect in the resonator. A shutter is positioned in the resonator and is configured to prohibit oscillation in the resonator until the lensing effect is stabilized. In one embodiment, diode-pumped laser oscillators are provided where damage to intracavity elements, such as SESAM'S, is prevented.
