Abstract :
We present the results of a laser resonator design that uses a 3-D volume gain grating formed by spatial hole-burning. The induced gain-grating can be considered a dynamic holographic element with diffractive properties that provide both spectral and spatial mode control of a high-gain flashlamp-pumped Nd:YAG laser system. The dynamic parametric growth of the grating initiated from amplified spontaneous emission in the cavity produces a self Q-switching resulting in short pulse formation
