Abstract
A center wavelength of first pulsed light (exciting pulsed light) is variable, and a pulse rate of the first pulsed light coincides with an integer multiple of a free spectral interval of an optical oscillator at a center wavelength of second pulsed light (signal pulsed light or idler pulsed light). A center wavelength of a nonlinear gain generated by a nonlinear optical medium is made approximately coincident with the center wavelength of the second pulsed light.
