✦ Synopsis

Lasers from Ho:YAG ceramic were reported in this paper. The Ho:YAG ceramic slab was end-pumped by a Tm:YLF laser whose central wavelength was 1.91 μm. At room temperature, with doping concentrations of 1 at.% Ho:YAG ceramic slab, continuous wave output power of 1.2 W at 2.09 μm was obtained under the absorbed pump power of 5 W, corresponding to a slope efficiency of 42.6% and a conversion efficiency of 24%.

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.

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 ab
