✦ Synopsis

In this paper, with Co 2+ :LaMgAl 11 O 19 (Co 2+ :LMA) crystals as the saturable absorber, the efficient passively Q-switched laser performance of a diode-endpumped Nd:Gd 3AlxGa5-xO12 (Nd:GAGG) laser at 1.33 μm has been realized. Under the absorbed pump power of 8.2 W, a maximum average output power of 450 mW was recorded with a Co 2+ :LMA crystal with an initial transmission of 90%. The minimum pulse duration was 14.6 ns, corresponding to the repetition rate of 3 kHz, the single pulse energy of 110 μJ and the pulse peak power of 7.1 kW.

The continuous wave (CW) and passively Qswitched Nd:Gd3AlxGa5-xO12 (Nd:GAGG) laser operation at 938 nm have been realized for the first time. The maximum CW output power of 0.44 W was obtained under the absorbed pump power of 8.54 W, corresponding to the slope efficiency of 7.8% and optical-to-optic

By using LT-GaAs as saturable absorber, we have demonstrated the stable Q-switched and mode-locked (QML) Nd:LuVO 4 laser run in a Z-type folded cavity. Nearly 100% modulation depth of mode locking can be obtained as long as the pump power reaches the oscillation threshold. The repetition rate of the

A diode-pumped doubly passively Q-switched Nd:LuVO4 laser with Cr 4+ :YAG saturable absorber and GaAs output coupler is realized. This laser can generate a shorter and more symmetric pulse profile when compared with pure GaAs. By using two Cr 4+ :YAG saturable absorbers with different small-signal t

By using both electric-optic (EO) modulator and GaAs saturable absorber, a doubly actively-passively Q-switched laser is realized for the first time. Especially, the more symmetric and shorter pulse is generated in comparison to purely EO-actively or GaAs-passively Q-switched laser. In addition, a s
