摘要： A fundamental wave is caused to enter a Cerenkov-radiation type optical wavelength converter device which is formed of a single-crystal organic nonlinear optical material of an orthorhombic system of mm2 point group disposed in a cladding as a waveguide and a wavelength-converted wave such as a second harmonic whose wavelength within the range of 430 to 500 nm is extracted. The wavelength of the fundamental wave is selected so that the wavelength of the wavelength-converted wave becomes longer than the absorption edge of the organic nonlinear optical material by at least 30 nm. The fundamental wave is linearly polarized in the direction of the x-optic-axis or the y-optic-axis of the crystal of the organic nonlinear optical material and then caused to enter the optical wavelength converter device, and a wavelength-converted wave which is linearly polarized in the z-optic-axis of the crystal is extracted.

摘要： A bulk crystal type optical wavelength converter device is made of a monocrystalline nonlinear optical material (3,5-dimethyl-1-(4-nitrophenyl)pyrazole, referred to as PRA). A linearly polarized fundamental having a wavelength ranging from 900 to 4000 nm is applied to the bulk monocrystalline nonlinear optical material to achieve angular phase matching of the type I for obtaining a second harmonic of the fundamental. An optical wavelength converter module comprises a fiber type optical wavelength converter device and a light source device. The optical wavelength converter device includes a core made of a monocrystal of the PRA which has a crystal orientation such that the c-axis thereof extends substantially along the axis of the core. The light source device applies, to the optical wavelength converter device, a fundamental which is linearly polarized in the direction of the a-axis or b-axis of the crystal which is normal to the c-axis.

摘要： An optical wavelength converter device of the optical fiber type comprises a core made of a nonlinear optical material and cladding of an amorphous material and surrounding the core, the cladding having a refractive index lower than the refractive index of the core. Another optical wavelength converter device comprises a two- or three-dimensional optical wavelength converter device produced by growing a nonlinear optical material crystal as an optical waveguide on or in an amorphous substrate having a refractive index lower than the refractive index of the nonlinear optical material crystal. Phase matching is achieved between a radiation mode of a wavelength-converted wave in the cladding or the substrate and a nonlinear polarized wave generated by a waveguide mode of first and second fundamental waves in the core or the optical waveguide.

摘要： An optical wavelength converting apparatus comprises a fundamental wave source, which produces a laser beam serving as a fundamental wave, and an optical wavelength converting device, which is provided with an optical waveguide constituted of a nonlinear optical material. The optical wavelength converting device converts a wavelength of the laser beam impinging upon and guided through the optical waveguide. The optical waveguide is provided with a plurality of periodic domain-inverted structures, which effect phase matching between the laser beam and wavelength-converted waves. Reflection of the fundamental wave or wavelength-converted waves from end faces of the optical wavelength converting device is thereby minimized, and a plurality of wavelength-converted waves having high intensities are obtained in a state combined with one another.

摘要： In an optical wavelength converting apparatus, a fundamental wave impinges upon a crystal of a nonlinear optical material, the type II of phase matching between the fundamental wave and its second harmonic is effected, and the second harmonic of the fundamental wave is thereby radiated out of the optical wavelength converting apparatus. Two crystals constituted of the same material are employed as the crystal. The two crystals have equal lengths and are located in orientations such that corresponding optic axes may be shifted 90.degree. from each other. The optical wavelength converting apparatus yields the second harmonic having the maximum possible output power and yet can be kept small in size and low in cost.
