Diode-pumped doubly Q-switched Nd:Lu0.33Y0.37Gd0.3VO4 laser with an electro-optic modulator and a single-walled carbon nanotube saturable absorber
2012
Abstract By simultaneously using an electro-optic (EO) modulator and a single-walled carbon nanotube saturable absorber (SWCNT-SA) in the cavity, a diode-pumped doubly Q-switched Nd:Lu 0.33 Y 0.37 Gd 0.3 VO 4 (Nd:LuYGdVO 4 ) laser is demonstrated. At the incident pump power 11.43 W and f =2 kHz, the minimum pulse width 17.6 ns and the maximum pulse peak power 19,886 W can be obtained. The experimental results show that this doubly Q-switched Nd:LuYGdVO 4 laser can generate shorter pulse width and higher peak power compared to the singly Q-switched Nd:LuYGdVO 4 laser with only EO or SWCNT-SA.
