Laser diode corner pumped Nd:KGW slab laser

Abstract

This paper reports the continuous wave (CW) and Q-switched operation of a diode pumped KGd (WO₄):Nd (Nd:KGW) slab laser with a corner pumped geometry at the wavelength of 1067 nm. With an optical conversion efficiency of 38% and 34%, average powers of 23 and 20 W in CW and Q-switched modes were achieved respectively. The maximum pulse energy of 27 mJ was observed with a repetition rate of 840 Hz.
