✦ Synopsis

A room-temperature diode-end-pumped acoustooptical (AO) Q-switched Tm:GdVO4 laser was firstly reported. The minimum AO Q-switch pulse width was measured to be about 48 ns with output power of 2 W and repetition rate of 5 kHz. Continuous-wave output power of 2.8 W at 1912 nm was obtained under the absorbed pump power of 15 W. In addition, laser pulse widths and the ratio of QCW power/CW power at different repetition rates were discussed.

In this letter we report a diode-pumped single frequency Tm:LuAG laser at room temperature. One uncoated fused silica etalon (0.1 mm) and one uncoated YAG etalon (1 mm) are employed to narrow the laser line-width. Single frequency laser is achieved by tuning the angle of the etalons.
