ABSTRACT:
An optical parametric diffuser is provided with an optical mixer which receives inputs of a probe light of a wavelength .lambda..sub.1 and a pumping light of a wavelength .lambda..sub.2, multiplexes them, and generates an output signal light including a wavelength .lambda..sub.5 which is apart from the pumping light wavelength on the opposite side of the probe light wavelength by n.DELTA..lambda. (.DELTA..lambda.=.vertline..lambda..sub.1 -.lambda..sub.2 .vertline., n.gtoreq.2). The signal of a wavelength .lambda..sub.5 is then extracted by a band-pass filter. The optical mixer is made to have a peak in output signal generation efficiency at the wavelength .lambda..sub.5 so that an output light beam of the wavelength .lambda..sub.5 can be obtained from the probe light and the pumping light.
