Abstract

Highly efficient continuous-wave and acousto-optically Q-switched laser emission in Nd:GdVO4 crystal, end-pumped at 879 nm into the laser emitting level, are reported. A maximum cw output power of 13.3 W is obtained, corresponding to the slope efficiency of 74.6% in absorbed power; an average output power of 12.1 W, a pulse width of 20.3 ns and a peak power of about 6 kW are reached at 100 kHz in A-O Q-switched operation.
