Abstract

The noise properties of quasi-phase-matched second-harmonic radiation with a grating feedback are studied for three different optical configurations. In multimode operation at a relatively low feedback rate from the grating to the laser diode the relative intensity noise for second-harmonic radiation is large. In single-mode operation at a high feedback rate it can be reduced to less than -130 dB/Hz. The critical value of feedback rate for the single-mode operation is the least, ∼8%, in the self-phase-matched configuration. The mechanism of second-harmonic noise under the multimode operation and the differences in the noise properties for these three configurations are also discussed.
