摘要： A light beam scanning system comprises a stack of a wave guide layer and an adjacent layer normally exhibiting a refractive index smaller than that of the wave guide layer, the wave guide layer and/or the adjacent layer being made of a material whose refractive index changes by the application of energy. Many energy application devices are positioned at the wave guide layer and/or the adjacent layer along an optical path of wave guided inside of the wave guide layer. Dielectric gratings are positioned on the adjacent layer so as to correspond to sections where energy is applied. A drive circuit is provided for sequentially and selectively energizing the energy application devices, and changing the refractive index of the wave guide layer and/or the adjacent layer so that the guided wave is radiated out of the stack by interaction with the dielectric gratings at the sections where energy is applied.

摘要： An image is formed in a color photosensitive material through scanning exposure by using at least one semiconductor laser excited solid laser including a semiconductor laser, a non-linear optical element and means for controlling the temperature thereof as a light source for producing a laser beam. The laser beam is modulated by an external modulator in accordance with the image to be formed. Among the combinations of photosensitive layers and laser beams, at least two laser beam light sources are such that a laser beam has a wavelength falling within .+-.20 nm from the maximum wavelength in the spectral sensitivity distribution of the corresponding photosensitive layer. Each photosensitive layer has a spectral sensitivity distribution with a peak width of up to 40 nm. The method enables to form an image in a conventional silver halide photosensitive material having spectral sensitivity in the visible region using a cost effective light source, the resulting image having color generated to a satisfactory density, free of a density variation, and hence of high quality.

摘要： A laser diode pumped solid laser comprises a solid laser medium, to which a rare earth metal has been added, a semiconductor laser, which produces a laser beam for pumping the solid laser medium, and a condensing lens, which causes the laser beam to converge in the solid laser medium. The condensing lens is located such that an optical axis of the condensing lens may deviate in the width direction of a semiconductor laser active layer from a center of irradiation area of the semiconductor laser. The amount of light returning to the semiconductor laser is thereby reduced markedly, and good stability in the output power of the laser diode pumped solid laser is obtained. A nonlinear optical material for converting the wavelength of a laser beam, which has been produced by the solid laser medium, into a different wavelength may be located in a solid laser resonator.

摘要： A light beam scanning system comprises a wave guide formed of a material allowing propagation of surface acoustic waves therethrough, and a means for generating the surface acoustic waves in the wave guide so that they advance along an optical path of light incident upon the wave guide, and a drive circuit for periodically applying a pulsewise voltage to the surface acoustic wave generating means. The wave guided inside of the wave guide is emitted out of the wave guide at the section where the surface acoustic waves are present by a coupling action of a grating generated by the surface acoustic waves with the guided wave.

摘要： An optical wavelength converting apparatus comprises an optical wavelength converting device, which is constituted of a crystal of a nonlinear optical material and converts a wavelength of an incident fundamental wave into a different wavelength, a holder, which is constituted of a metal and to which the optical wavelength converting device is adhered and secured, and a device for adjusting the temperature of the region containing the optical wavelength converting device. The optical wavelength converting device is secured to the holder by adhering only the surface of the optical wavelength converting device to the holder, which surface is normal to the direction of a crystallographic axis that has a coefficient of thermal expansion most different from the coefficient of thermal expansion of the metal constituting the holder among the coefficients of thermal expansion of the crystallographic axes of the optical wavelength converting device. The optical wavelength converting device is thus reliably secured to the holder and prevented from breaking or being distorted due to a change in environmental temperature, and the accuracy, with which the temperature of the optical wavelength converting device is adjusted, is kept high.
