Abstract

A microchip cavity including a half-monolithic Nd:YAGKNbO3 chip and a second KNbO3 crystal is presented. An output power of up to 30 mW at 473 nm pumped by a single stripe 1-W at 808-nm diode is achieved. The laser can be operated in either single-longitudinal or multilongitudinal mode by rotation of the second frequency-doubling crystal to 0° or 90° from the first one. The cw output noise is less than 2% for both cases.
