Passively mode-locked quasi-continuously end-pumped Yb:YAG laser at room and cryogenic temperatures
Original language description
In this work, we have investigated operation of a quasi-continuously diode pumped Yb:YAG laser at room and cryogenic temperatures. In free-running regime, an increase in laser eciency has been observed from 52 % optical-to-optical eciency at room temperature to 69 % at 92 K. With passive mode-locking, the laser operated with higher eciency and stability against Q-switching instabilities when the laser crystal was cooled to cryogenic temperatures. On the other hand, increase in pulse duration as a consequence of linewidth narrowing has been observed. At room temperature, pulses with duration of 2.8 ps were generated with 4 % optical-to-optical eciency, compared to 11.8 ps pulse duration and 13 % optical-to-optical eciency at 85 K.
