A semiconductor harmonic generating device comprising a nonlinear medium and a waveguide which is provided in the upper face of the nonlinear medium. A higher harmonic laser light from a fundamental wave laser light which passes through the waveguide, wherein the waveguide has refractive index dispersion means for counterbalancing the refractive index difference caused by wavelength dispersion, occurring in the nonlinear medium, between the fundamental wave laser light and the higher harmonic laser light.
