ABSTRACT:
An optical wavelength shifter shifts a wavelength of light over a wide range without need for using a large peak pump pulse. A nonlinear optical medium having a nonlinear refractive index is disposed interiorly of a laser resonator. A pump pulse and a light to be modulated are incident on a nonlinear optical medium to phase shift the light. With the provision of a timing delay unit, the timing at which the light to be modulated is incident on the nonlinear optical medium is delayed with respect to the timing at which the pump pulse is incident thereon.
