Abstract
Grating feedback optics is shown to contribute to narrowing the spectral bandwidth of a multilongitudinalmode laser diode to less than 0.2 nm and tuning the lasing wavelength to the peak absorption wavelength of Nd:YVO4. A continuous green light of 31 mW was efficiently generated by intracavity frequency doubling of the Nd:YVO4 laser with a KTiOPO4 crystal. A relative intensity noise of less than −140 dB/Hz was obtained in the frequency region greater than 2 MHz. The noise characteristics of generated green light are discussed as compared with the case of using a single-longitudinal-mode laser diode as the pumping source.
