We present a semimonolithic frequency-doubler from 1080 to 540 nm with 80% doubling efficiency and up to 849-mW output power of green light. A frequency-stabilized laser diode (LD) pumped continuous wave (CW) Nd:YAP laser is used as the pump source of the doubler consisting of an ?-cut KTP crystal and an input mirror. The frequency stabilities of the output second harmonic wave are better than +/-246 kHz and +/-2.3 MHz in 1 and 30 minutes, respectively, and the intensity fluctuation is less than +/-0.65%.
