Abstract:
We demonstrate a simple, compact and highly-efficient L-cavity-thulium-doped laser system working at room temperature.The Tm-doped Tm∶YAP crystal is pumped by two 793 nm laser diodes at both ends of the crystal. Mole fraction of the Tm3+ in Tm∶YAP crystal is 3%. With an incident pump power of 120 W, a maximum continuous-wave output power of 42 W is obtained at 1 988 nm. The average power of 39.4 W, a peak power of 16 kW, a single pulse energy of 3.94 mJ and a pulse width of 247.5 ns are achieved at pulse recurrence frequency of 10 kHz under an incident pump power of 120 W by using an acousto-optic Q-switch, and the slope efficiency is 35%.
