Abstract :
Most pulsed solid-state lasers operating in a normal (long-pulse) mode exhibit transient spiking behavior, characteristic of relaxation oscillations. Suppression of this spiking behavior can be achieved using a number of passive techniques. In this paper, we describe the use of intracavity second-harmonic generation to achieve smooth, long-pulse operation of a flashpumped 2 μm Cr,Tm:YAG laser
