A frequency-doubled and frequency-stabilized ring Nd:YAP laser with a six-mirror cavity is demonstrated. This laser satisfies both the thermal insensitivity and optimal frequency-doubling conditions. A second-harmonic output to 1 W at 0.54 μm is achieved. The intensity fluctuation is less than ∓1.5% and the frequency stability is better than ∓1 MHz (5 min).
