Abstract

A high-power high-beam-quality 1064nm Nd:YAG rod laser and SHG by intracavity-frequency-doubling are reported. With two common side-pumped Nd:YAG rod modules in the short cavity, we achieved an 78.5W near diffraction-limited pulsed wave 1064nm laser(M²=1.5) with pulse frequency 30kHz, pulse width 94ns and a good power stability of ±1% for over two hours. Finally, a 40W pulsed green laser with pulse width of 92ns in a near diffraction-limited beam (M²=1.45) is generated using an LBO crystal as the frequency doubler in the cavity.
