A 10 W Diode-Pumped Solid-State Green Laser

This paper reports a 10 W solid state green laser TEM00 mode output operation, pumped by 3 x 40 W LD arrays. The theoretical analysis of the cavity stability and operation mode selection are presented. To make the system more compact, a Brewster plate is specially designed to function both as a polariser as well as a green output coupler.In the experiment, we obtain maximum 10 W green laser TEM00 output at 10 kHz by establishing a concave-flat stable resonator. Angle mismatch in the frequency doubling is corrected by optimising the crystal temperature to maximise the laser output. The system is completely enclosed in a customised chassis, enabling further integration of scanner head for application testings as well as inhibiting environmental factors that will affect the performance of the laser.
