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 laser optical system includes a linear beam forming member for forming laser beams radiated from laser oscillators into a linear beam shape on a silicon film on a substrate. The laser optical system is arranged so that the optical axes of laser beams from the laser oscillators to the linear beam forming member are in substantially the same plane and substantially perpendicular to the substrate. Each laser beam is reflected from a reflecting mirror and applied to the silicon film on the substrate. Since the laser beams are applied to the substrate at the same time, the area irradiated can be increased, while each radiating laser beam maintains a required radiation intensity, resulting in high productivity.

摘要： A digital mirror dence chip has a substrate, micro-mirrors disposed on the substrate, and a glass cover plate disposed over the micro-mirrors. Each micro-mirror is inclined by +10 degrees or −10 degrees with respect to the substrate to be set to an on-state or an off-state. Incident light produced in a lighting source system is totally reflected in a total internal reflection prism and is incident on the micro-mirrors through the glass cover plate. Outgoing light reflected by micro-minors in the on-state passes through a projection lens and is projected onto a screen to form an image on the screen. Also, outgoing light reflected by micro-mirrors in the off-state passes out of the projection lens. The glass cover plate is not parallel to the substrate. Therefore, light specularly reflected by a surface of the glass cover plate passes out of the projection lens.

摘要： A laser power supply apparatus supplies AC power to a gas contained in a laser device by way of a pair of dielectric layers, without having to use a transformer to form a high-frequency discharge in a gas to excite the gas, to cause the laser device to radiate. The laser power supply apparatus includes an inverter having arms, each arm including high-speed semiconductor switches connected in series, for directly converting a DC high voltage from a DC power supply to a series of AC output pulses having a much higher AC voltage than the DC high voltage and supplied to the laser device by simultaneously turning on and off those high-speed semiconductor switches in each of the arms, and for furnishing the series of AC output pulses to the laser device at a pair of output terminals.

摘要： A laser system wherein, in order that a high-output and high-quality single mode of a cross sectional area larger than the beam diameter determined by the construction of a resonator can be obtained stably, although this has heretofore been impossible, there is used a coupling mirror provided with a partial reflection film and an antireflecting film, a laser beam mode is selected using the partial reflection film, a phase difference between laser beam portions caused by a difference in construction between the partial reflection film and the antireflecting film is compensated using a phase difference compensating apparatus, and there is formed an aperture whose diameter is set to a value of not larger than four times the diameter of the partial reflection film.
