Abstract
Detailed oscillation spectra and polarization properties of laser-diode-pumped ceramic Nd: YAG lasers were examined. Inherent segregation of lasing patterns into local modes possessing different polarization states and oscillation frequencies was observed. Single-frequency, linearly polarized stable oscillations were achieved by forcing the laser into Ince-Gaussian mode operation by adjusting azimuthal cavity symmetry.
