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： There is disclosed a medium attaching device and a disk drive apparatus which are suited for a compact and lightweight design and a thin design, and are capable of automatic attachment of a disk. The device includes a rotary support device for holding a disk medium thereon, and a rotation drive device for rotating the rotary support means so as to rotate the disk medium. The rotation drive device includes a reciprocally-moving device for reciprocal movement in a direction of an axis of a rotation shaft. The rotary support device has a plurality of pivotal attaching devices pivotally mounted thereon, and each of the pivotal attaching devices is pivotally movable between a fixed position where the pivotal attaching device fixedly holds the disk medium and a received position where the pivotal attaching device is received in the rotary support device. The plurality of pivotal attaching devices are provided on the rotary support device in concentric relation to the axis of the rotation shaft. The pivotal attaching devices are engaged with the reciprocally-moving device, and are pivotally moved by the reciprocal movement of the reciprocally-moving device, thereby fixing and releasing the disk medium relative to the rotary support device.
