摘　　要：A highly efficient and high power green laser generated by intracavity frequency doubling of a diode-side-pumped Q-switched Nd:YAG laser has been demonstrated.In the simple L-shaped cavity geometry,the maximum green output power of 28.5 W was obtained with a pulse width of 95 ns at a pulse repetition rate of 10 kHz by using a LBO crystal for frequency doubling,corresponding to a conversion efficiency of 11% from diode pump power to pulse green power.At a pulse repetition rate of 1 kHz,6.9 mJ of pulse energy,25 ns of pulse duration and 276 kW of peak power were obtained.A highly efficient and high power green laser generated by intracavity frequency doubling of a diode-sidepumped Q-switched Nd：YAG laser has been demonstrated.
