Abstract
A diode-end-pumped electro-optic (EO) Q-switched green laser operating at the repetition rate of 20 kHz is reported. A block of La<sub>3</sub>Ga<sub>5</sub>SiO<sub>14</sub> (LGS) single crystal is used as a Q-switch and the type I phase-matching LiB<sub>3</sub>O<sub>5</sub> (LBO) is used as the nonlinear crystal in the second harmonic generation. The 2.3-Waverage power of 532-nm green laser is obtained at the repetition rate of 20 kHz with the pulse width as short as 10 ns. When the output power is about 1.5 W, the measured power fluctuation is less than 1.4% (root-mean-square, RMS) with the beam quality factor of M<sup>2</sup><2 in both orthogonal directions.
