Abstract

We have observed giant pulses from cw pumped, monolithic Nd:YVO4 microchip lasers, several hundred times the cw level, with pulse lengths less than 2  ns, which cannot be accounted for by conventional gain switching. These pulses occur as the second longitudinal mode starts to oscillate and can be described by the inclusion of gain-related effects in the formation of a stable cavity.
