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.

摘要： A method for producing domain reversals at predetermined periods deep into a MgO-LN substrate or a MgO-LT substrate in a highly controllable manner without entailing the destruction of crystals of the substrate. Proton-exchanged regions are produced in a predetermined pattern on a unipolarized MgO-LN substrate, and a substrate having a doping level of MgO ranging between 3 mol. % and 9 mol. % is used as the MgO-LN substrate when these proton-exchanged regions are changed to localized domain reversals by applying an electric field to the proton-exchanged regions from a high voltage power source via a corona wire.

摘要： A method for fabricating an optical wavelength converter element which has a high optical damage threshold value, and is capable of achieving a high wavelength conversion efficiency without involving propagation losses caused by the reflection and scattering of a fundamental wave and a wavelength-converted wave. Domain reversals periodically arranged are formed on a substrate made of a LiNbO.sub.3 crystal which acts as a ferroelectric substance possessing a nonlinear optical effect. Thereafter, an ITO thin film made of a transparent electrically conductive material is deposited on a surface of the substrate extending in the direction of the arrangement of the domain reversals, that is, "y" and "z" surfaces.

摘要： A fabrication method in which periodic domain reversals of large area are formed deeply, under improved control, over a ferroelectric which possesses the nonlinear optical effect. Proton-exchanged regions are prepared in a predetermined pattern on a unipolarized MgO-LiNbO3 substrate. An electric field is applied to these proton-exchanged regions from a high voltage power supply via a corona wire while it is subjected to a heat treatment by a heater, thereby fabricating local domain reversals.

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： A rotation control device is configured so that a spring force of a torsion coil spring holds an attitude of a rotation body at a pre-advancement position corresponding to a post-return position (a), and a post-advancement position corresponding to a pre-return position (b), respectively. The rotation control device includes a first rotation part supporting one end of the torsion coil spring and supported on a fixed body so as to rotate as the rotation body rotates, and a second rotation part rotatably supported on the fixed body at a first rotation part side and supporting the other end of the torsion coil spring. When the first rotation part rotates, the second rotation part rotates together with the first rotation part. A wound portion of the torsion coil spring is most elastically deformed when the rotation body is at an intermediate position (c) between the position (a) and the position (b).
