    摘要： In order to reduce manufacturing cost of a base supporting a semiconductor laser, without deteriorating accuracy of mounting of the semiconductor laser, a mounting member is provided between the base supporting the semiconductor laser and the semiconductor laser; and the semiconductor laser and the base are fixedly attached with heat-cured silver paste. The silver paste has a lower curing temperature than an assurance temperature of the semiconductor laser, and a higher heat resistance than an operation temperature of the semiconductor laser. The mounting member is formed of a material having a higher heat resistance than the curing temperature of the silver paste.

    摘要： In a laser light source apparatus using a wavelength converting device (35), the position and angle of the wavelength converting device are allowed to be varied so as to maximize the laser output. The angular adjustment of the wavelength converting device is simplified by accurately positioning the wavelength converting device. A holder (57) for retaining the wavelength converting device may be supported by a support portion (56) formed in a base (38) so as to be moveable in the depthwise direction of the poled inverted domain regions and tiltable with respect to the optical path. Preferably, the holder may be rotatable around an axial line substantially perpendicular to the optical axial line. In particular, the wavelength converting device may be fixedly attached to the holder so as to bring an exit surface (35b) of the wavelength converting device in close contact with a mounting reference surface (841) by using a bonding agent applied to a top surface (35e) and a bottom surface (35f) of the wavelength converting device adjacent to the exit surface, and a bottom surface (207) of a recess (891) formed in the holder adjacent to and in parallel with the mounting reference surface.

    摘要： The present invention provides an image display apparatus which includes a red color laser light source that outputs red color laser light; a blue color laser light source that outputs blue color laser light; and a green color laser light source that outputs green color laser light. Further, the green color laser light source includes a semiconductor laser that emits non-visible light; and a wavelength convertor that converts the non-visible light to visible light and thereby outputs a green color laser. Furthermore, the image display apparatus has a projecting lens that outputs the laser light of the respective colors; and a case that retains the red color laser light source, the blue color laser light source, and the projecting lens. The case has a protrusion that retains the green color laser light source.
