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 a new saturable absorber V 3+ :YAG, a flashlamp-pumped passively Q-switched Nd:GdVO 4 laser at 1.34 ยตm has been realized. Both a-cut and c-cut Nd:GdVO4 crystals are used. The output single-pulse energy and the pulse width versus the pump energy for different initial transmissions of V 3+ :Y
We report on the passively Q-switched mode-locking of a quasi-cw (QCW) diode pumped Nd:GdVO 4 laser with Cr 4+ :YAG saturable absorber. We show that by using the QCW pumping high quality Q-switched mode-locking can be easily obtained in the laser even with a simple two-mirror laser cavity configurat
