Abstract :
Diode-pumped 1.9-μm Tm:KYW microchip laser with 1.6 W TEM00 cw output power operates with 72% slope efficiency relative to the absorbed pump power. Output power of 2.5 W is achieved with generation of a doughnut transverse mode. Q-switched laser operation with pulse duration of 2.2 ns at 1.5 MHz repetition rate is demonstrated.
