Abstract

PURPOSE:To obtain short wavelength laser radiation having a narrow spectrum bandwidth and high coherency, by doping a medium having nonlinear optical effect with active ions, and making single element oscillate laser radiation and generate higher harmonics by virtue of nonlinear optical effect. CONSTITUTION:A light radiated from a semiconductor laser 140, whose wavelength is 810nm, is transmitted through a reflection film 120, and guided to an optical waveguide 110. The guided light excites Nd being active ion, and emitts 109nm wavelength fluorescence, which is amplified in an optical resonator constituted of reflection films 120, 130 and the optical waveguide 110. Since LiNbO3 crystal has nonlinear optical effect, 545nm wavelength higher harmonic is generated. When the waveguide is 2mum wide, 0.55mum deep, and 6mm long, the higher harmonic turns to radiation mode as the result of phase matching. Therefore, 545nm wavelength light is radiated at an inclination angle of 12.5 degree to the surface, by the effect of what is called Cherenkov radiation.
