A scattering-loss-structure portion composed of a low refractive-index region is disposed around a main current path in a surface-emitting semiconductor laser, namely around a cavity structure portion; the low refractive-index region is disposed at intervals; and the shape of the tip portion opposing to the center portion is set to be a tapered shape, for example, at an acute angle. Accordingly, in the cavity structure portion, the loss of light-emitting laser of a high-order mode localized in the outer circumferential portion becomes large, so that a surface-emitting semiconductor laser that oscillates the single-mode laser with favorable performance is constructed.

摘要： The battery charging detects battery temperature and includes a temperature maintaining charging operation wherein average charging current is controlled to drive battery temperature to a holding temperature, and charging is performed while maintaining battery temperature at that holding temperature. In addition, a temperature increasing charging operation occurs prior to the temperature maintaining charging operation. The battery is charged with a current which raises battery temperature until the holding temperature is reached. When battery temperature rises to the holding temperature in the temperature increasing charging operation, charging can transition to the temperature maintaining charging operation.
