摘要：

The highly efficient performance of a Cr,Nd:YAG/KTP intracavity frequency doubled self-Q-switched miniature green laser is demonstrated at room temperature. The average output power of an over-1-W green laser at 531.5 nm is obtained at the absorbed pump power of 7.3 W. The slope efficiency and optical-to-optical efficiency are as high as 22.2% and 13.7%, respectively. The laser pulses with pulse width less than 6 ns, pulse energy of 12 mu J, and peak power of over 2 kW are achieved. The laser works from several to 76.5 kHz, depending on the pump power levels. A near diffraction limited laser beam with M-2 less than 1.5 is achieved in this miniature green laser.
