摘要： A wavelength conversion apparatus in which output direction of a wavelength-converted laser beam, having a wavelength converted by a nonlinear optical crystal and emitted through an output-window, can be brought close to the direction of optical axis of the laser beam passing through the nonlinear optical crystal. In addition, axial deviation of the wavelength-converted laser beam converted by the nonlinear optical crystal and emitted through an output-window, can be reduced when the position of the nonlinear optical crystal is moved. The output facet of the nonlinear optical crystal is inclined at Brewster's angle with respect to the wavelength-converted laser beam. An output-window of a case containing the nonlinear optical crystal has a prism form in which the distance between a laser beam input facet and a laser beam output facet of the output-window is reduced along a direction in which the wavelength-converted laser beam, emitted from the nonlinear optical crystal, inclines.

摘要： An optical wavelength conversion element includes a cesium-lithium-borate crystal processed into a 10-mm long optical element cut in an orientation that allows a fourth harmonic of a Nd:YAG laser to be generated. A transmittance (Ta) at 3589 cm−1 in an infrared transmission spectrum of the optical element is used as an index that indicates a content of water impurities in the crystal and is independent of a polarization direction. An actual measurement of the transmittance Ta is at least 1%, without taking into account loss at an optically polished surface of the crystal. A wavelength conversion device, a ultraviolet laser irradiation apparatus, a laser processing system, and a method of manufacturing an optical wavelength conversion element are also described.

摘要： A lamp has a deformed lamp reflector and a lamp front glass. The deformed lamp reflector is formed by deforming a paraboloid of revolution of a conventional lamp reflector to an aspherical reflection surface which is rotationally symmetrical with respect to an optical axis. The lamp front glass is obtained by deforming the incident plane of a conventional lamp front glass to an aspherical lens surface rotationally symmetric with respect to the optical axis. A light flux radiated from the center point of the light source of an illuminant is reflected by the deformed lamp reflector, and is output through the lens as a parallel light flux having a circular cross section equal in area to the lens.

摘要： An optical system that controls laser beam spot profile for forming a high performance thin film by a laser heat treatment process is provided. In the optical system that irradiates a rectangular laser beam on a film formed on a substrate, intensity distribution forming, apparatus makes the intensity distribution uniform in the longitudinal direction while maintaining the properties of the laser beam 2 such as directivity in the direction of shorter side, making it possible to concentrate the light to a limit permitted by the nature of the laser beam and achieve the maximum intensity gradient on the film disposed on the substrate. Thus a steep temperature distribution can be generated on the film disposed on the substrate and, as a result, high performance thin film can be formed.
