Study of passive Q switching for flash lamp pumped 1.34 micron Nd:GdVO4 laser

The static laser performance of a-growth Nd:GdVO4 crystal (a-cut, 4*4*25 (mm)) at 1.34 micron pumped by flash-lamp is investigated with different transmissions of output couplers. With the output coupler transmission of T=30%, the static output energy of 148 mJ is obtained when the pump energy is 35
