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： 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： In a disclosed laser module, a usage amount of organic adhesive is set to no more than 1.0 g/ml. Thus, an equilibrium density of outgas components from the adhesive after an air removal treatment is less than 1000 ppm. In another laser module, a heat sink at which a semiconductor laser element is adhered on a submount, an electrode terminal wire-connected with the laser element, a photodiode wire-connected with the electrode terminal, and a zeolite adsorbent are fixedly provided on a stem. These are ring-welded in a container in a dry air atmosphere (80% nitrogen, 20% oxygen). In still another laser module, sixteen multiplexed lasers are disposed in a container. The container is connected with an air circulation apparatus, which is provided with a filter for removing contaminants, a rotary pump for circulating inert gas, and a valve for controlling replenishment of the gas.
