We report here on a new compact frequency-doubled Nd:YVO4 laser emitting up to 165 mW of single frequency, TEM00 mode, 532 nm green laser output. This compact, high efficiency, single frequency laser incorporating a novel coupled cavity technology appears promising for use in holographics and the printing industry. This coupled cavity technology provides for a frequency-doubled laser capable of operating in single longitudinal mode while eliminating many intracavity optical components, such as polarizers, waveplates or etalons. The few intracavity elements include a KTP nonlinear optical crystal employed for intracavity frequency doubling. The reduced component count results in a dramatic reduction in optical losses in the laser cavity and increased efficiency. This laser device produces 165 mW of green laser output power from a 1 W pumping laser diode, illustrating that both power and efficiency are improved using this technology. The reduced components also allow for a more compact laser, with the laser head measuring 3 X 3 X 12 cm, and the power control unit measuring 5 X 13 X 15 cm. This laser also features excellent output stability with power variation less than 1% over 4 hours, and less than 0.5% amplitude noise in the 10 Hz to 560 MHz bandwidth range.
