We have developed a 473nm blue light generation source by frequency doubling using a KNbO₃ for intracavity second harmonic generation of a laser diode pumped Nd:YAG 946nm laser which is combined with an auto power control system and a temperature control for the entire resonator. We tried to stabilize the output power with the results that the fluctuation is less than ±1% at 15mW of blue light under a wide environmental temperature range of 0°C and 45°C.
