A diode-pumped continuous-wave Yb:KGW laser with Ng-axis polarized output

摘要

A diode-pumped continuous-wave Yb:KGW laser with radiation polarized along the N_g-axis is reported. The laser delivered more than 1 W of average power at 1029 nm with a slope efficiency of 28% and excitation at 980 nm. The ratio of the stimulated emission cross sections for the N_m- and N_g polarizations was experimentally determined to be close to 5 at the laser wavelength.
