摘要：
A continuous-wave (CW) and passively Q-switched Tm:Y2O3 ceramic laser emitting at 2.1 mu m were reported for the first time. A volume Bragg grating (VBG) acted as the input mirror which enables wavelength selection of the Tm: Y2O3 laser. The gold-nanorods-based saturable output coupler combined the function of passive Q-switching and output coupling. In the CW mode, the VBG-locked Tm:Y2O3 ceramic laser generated 1.1 W at 2101.5 nm with a linewidth (FWHM) of 0.4 nm. In the passively Q-switched operation, pulses with a maximum average output power of 455 mW, a minimum pulse width of 609 ns, and a pulse repetition rate of 79 kHz were achieved. Our work provides a more compact and efficient design for obtaining a nanosecond 2.1 mu m laser. (C) 2017 Optical Society of America
