Abstract
By using GaAs wafer as the saturable absorber the laserdiode pumped passively Qswitched composite NdYVO 4 laser has been successfully demonstrated For this passively Qswitched operation the average output power obtained is as high as 846 mW at the incident pump power of 531 W while the pulse duration is as short as 145 ns The largest singlepulse energy of 249 upmu J and the highest peak power of 166 W are obtained The GaAs saturable absorber with thickness of 400 upmu m has shown more excellent laser performance comparing with 700 upmu m thick GaAs
