| Abstract: | A diode end-pumped passively Q-switched Nd: Y0.8Lu0.2VO4 laser with a Cr4+: YAG crystal is first demonstrated in this paper. The maximum continuous wave (CW) output power of 5.59 W is obtained at the incident pump power of 13.07 W with the output transmission T = 20%, resulting in an optical-to-optical efficiency of 42.7%. For Q-switching operation, the measured pulse duration of 8.5 ns, the pulse energy of 45.24 μJ and the peak power of 5.32 kW are respectively obtained for the output transmission of 50% when the Cr4+: YAG crystal is used with an initial transmission (T0) of 60%. |
