Abstract
A wavelength converter having the light source formed of the semiconductor laser 1 and the nonlinear optical element 2, wherein, the oscillation light therefrom is incident to the nonlinear optical element 2 as an input fundamental wave, and the oscillation wavelength is changed by the very small variation current added to the injection current to the semiconductor laser so that the input fundamental wavelength to the nonlinear optical element 2 is changed and that the oscillation wavelength of the semiconductor laser is pulled in the input fundamental wavelength at which the wavelength conversion efficiency is the maximum.
