Abstract
The intensity noise of a CW-operated semiconductor Raman laser with a tapered waveguide structure with GaP core and AlxGa1-xP cladding layer s has been measured and it has been found that the noise spectral inte nsity in the frequency range 10 Hz-100 kHz was reduced to 34 dB below that of the incident pump light under saturation conditions. This effe ct has been interpreted as coupling between the pump light, the first Stokes light and the second Stokes light, assuming a very small contri bution of nonlinear absorption.
