SPONTANEOUS SINGLE-FREQUENCY OUTPUT FROM A SPATIALLY HOMOGENEOUS Nd:YAG LASER

Abstract
By moving a Nd:YAG rod relative to the cavity field with velocities of the order of centimeters per second, we obtained single‐frequency oscillation close to the center of the gain curve with output powers up to 1.2 W. Our results can be understood quantitatively by considering the smoothing effect of the relative motion on the spatial distribution of the population inversion.
