Abstract

Efficient, room-temperature operation of a Tm:YAG laser, end-pumped by the re-shaped output beam from a 20W diode-bar, is reported. At a rod mount temperature of 20°C and with 13.5W of diode pump power incident on the Tm:YAG rod we obtained 4.1W of output at 2.013µm in a near-diffraction-limited beam with corresponding M2 values in orthogonal planes of 1.4 and 1.2. The prospects for further power-scaling are discussed.
