    摘要： A laser apparatus includes an excitation light generator for emitting excitation light and a wavelength converter including a solid laser medium for emitting laser light by converting a wavelength of the excitation light. The excitation light generator includes a surface-emitting laser having a first reflector with top and bottom reflectors and an active layer disposed between the top and bottom reflectors. The excitation light generator further includes a second reflector configured to highly reflect the excitation light. The solid laser medium is disposed between the surface-emitting laser device and the second reflector. Reflectivities of the top and bottom reflectors of the first reflector are set so that FWHM of the solid laser medium at the wavelength of the excitation light is greater than a resonance wavelength range of the surface-emitting laser device.

    摘要： A CMIS transistor suitable for device miniaturization, elimination of degradation of operational characteristics by hot carrier effect, and elimination of decrease of threshold voltage caused by short channel effect, includes a laterally spreading N-type diffusion region having an impurity concentration level higher than P-type and N-type wells but lower than source and drain regions, such that the N-type diffusion region extends laterally into a part located immediately below an edge of an insulating gate and has a depth smaller than a depth of the source and drain regions. The device is thereby capable of increasing the width of depletion layer at the bottom of the source and drain regions while maintaining effectiveness as a punch-thorough stopper. Thereby, the junction capacitance at the source and drain regions is reduced and the operational speed of the device improved in the P-channel transistor part in the device. In the N-channel transistor part, an effective suppression of punch-through is achieved because of the small diffusion depth of the N-type diffusion region. Thereby, the decrease of threshold voltage caused by the short channel effect is effectively eliminated even when the gate length of the transistor is reduced.

    摘要： In performing an light emitting operation using a plurality of semiconductor light-emitting devices, these semiconductor light-emitting devices are lighted up such that the driving current is lessened and the life time of the devices is prevented from being shortened and lights can be emitted to a remote site without reducing an amount of lights. Semiconductor laser devices 23a to 23c, which emit lights through independent lenses 25a to 25c, are connected in series to each other and connected to a signal generating circuit 24, serving as a power supply, so as to perform pulse lighting, whereby making it possible to light up three semiconductor laser devices simultaneously at a driving current corresponding to one semiconductor laser device. A package of semiconductor laser devices 23a to 23c comprises three lead terminals, and an electrical connection to two lead terminals, which are electrically insulated from a metallic base, is established. If a light collection point P is positioned in the midway of the detection distance range, the shifting quantity of the laser beams is minimized over substantially the entire area so that the amount of lights can be suppressed.

    摘要： An active layer in which laser light is generated by injecting driving current therein is sandwiched between semiconductor layers. The active layer has a multi-quantum-well structure, and the layers located at both sides of the active layer are made of an AlGaAs-based material. Refractive indices of the layers are set asymmetrically with respect to the active layer by properly selecting aluminum-mixing ratios in AlGa. Since the light generated in the active layer is distributed more in a layer having a higher refractive index, a peak of the light distribution is shifted from the active layer into the layer having a higher refractive index. Thus, energy concentration to the active layer is avoided. A thickness of the layer having a higher refractive index may be made thicker to further enhance the energy concentration shift from the active layer.
