Abstract

A resonator configuration which couples out the Gaussian TEM₀₀ mode was demonstrated to suppress low-frequency relaxation oscillations in the output from a long-pulse Nd:YAG laser. Experimental measurements of the spatial and temporal beam quality, the spectral bandwidth, and the depth of amplitude modulation were made for this and several other Nd:YAG laser resonator designs. The result of these measurements indicates that this resonator configuration can be used to generate a high-quality (TEM₀₀) long-pulse laser output which is nearly free from relaxation oscillations.
