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： Angle adjustment of a wavelength conversion element after assembly is eliminated to achieve a reduction in production cost with a simplified structure. An element holder provided on a base that supports the wavelength conversion element is provided with a mounting reference surface that positions the wavelength conversion element in parallel with an optical axis. The wavelength conversion element has a substantially parallelepiped shape. A bottom surface, which is one of the four surfaces adjacent to an incident surface and an output surface, is in contact with the mounting reference surface, such that a depth direction of inverted polarization regions is substantially orthogonal to the optical axis and the incident surface and the output surface are tilted at a predetermined tilt angle relative to a flat surface orthogonal to the optical axis.

摘要： Top surfaces and inclined surfaces of prisms on a side opposite to a light source are formed such that, in a region on a light source side, light traveling in a light guide body toward the side opposite to the light source is sequentially reflected by the top surfaces and the inclined surfaces of the side opposite to the light surface of the prisms and approaches a direction orthogonal to the longitudinal direction of the light guide body. The height of the prisms can be the lowest in the longitudinally central portion of the light guide body, and gradually increases toward the light source side and the side opposite to the light source, from the central portion.

摘要： The present invention provides an image display apparatus that includes a case having an air inlet port and an exhaust port; a cooling air passage that is formed by connecting the air inlet port and the exhaust port; and an optical unit that is provided within the case. The optical unit includes a red color laser light source, a green color laser light source, and a blue color laser light source, and these laser light sources are positioned in the cooling air passage. Further, the image display apparatus has an air blower that cools the laser light sources of the respective colors by introducing air from the air inlet port and exhausting air from the exhaust port; and a lens that is provided on the light-emitting side of the laser light sources. The red color laser light source is positioned closer to an upstream side of the cooling air passage than the green color laser light source and the blue color laser light source. With this, the temperature of the red color laser light source apparatus is not increased by a long period of use, and thereby image quality deterioration is prevented.
