Abstract:
1. A harmonic wave oscillating system comprising: a solid-state laser oscillator; a waveguide-type harmonic wave oscillating device comprising a converting optical waveguide converting a wavelength of a laser light oscillated from said solid-state laser oscillator to oscillate a harmonic wave, an incident-side end face of said laser light, an emitting-side end face of said harmonic wave, a first side face and a second side face; a first lens system condensing said laser light oscillated from said solid-state laser oscillator to said incident-side end face of said waveguide-type harmonic wave oscillating device; and a second lens system condensing said harmonic wave emitted from said emitting-side end face of said waveguide-type harmonic wave oscillating device; wherein said emitting-side end face comprises a polished surface formed on the side of said first side face and a light scattering surface formed on the side of said second side face, wherein an angle θ of said first side face and said polished surface is an obtuse angle, and wherein an angle α of said second side face and said light scattering surface is an obtuse or right angle.
