An output power of more than 5.5mW at 531nm was obtained from a single-frequency green laser using a microchip NYAB (NdxY1-xAl3 (Bo3) 4) crystal. Microchip laser was constructed a 500 μm cavity length and pumped by a diode laser at 480mW with an optical fiber. The slope efficiency was 1.46% and the stability of output power was less than ± 0.2%.
