Abstract

We present a near diffraction-limited 1 064-nm Nd:YAG rod laser with output power of 82.3W(M2 \approx 1.38). The power fluctuation over two hours is better than \pm 1.1%. Pulsed 1 064-nm laser with an average power of 66.6 W and pulse width of 46 ns are achieved when the laser is Q-switched at a repetition rate of 10 kHz. The short pulse duration stems from the short cavity as well as the high-gain laser modules. Using intracavity-frequency-doubling, a 35.0-W near diffraction-limited 532-nm green laser (M2 \approx 1.32) is achieved with a pulse width of 43 ns.
