摘要： A wavelength conversion element is provided with a substrate including a nonlinear optical single crystal having a periodically poled structure, the visible light transmittance of the substrate is 85% or higher when ultraviolet light is irradiated to the substrate, and laser light having an average output of 1 W or more is outputted by shortening the wavelength of laser light having a wavelength of 640 nm to 2000 nm. By improving visible light transmission characteristics when the ultraviolet light is irradiated in this way, the breakdown of crystal can be prevented and the stabilization of output characteristics at high output can be realized. As a result, the absorption of green light induced by ultraviolet light can also be suppressed, and the saturation of output and the breakdown of crystal can be avoided.

摘要： A light source emits a light beam which is focused on an optical recording medium. The light beam is reflected and diffracted by the optical recording medium. A holographic optical element has divided regions formed with different holographic patterns. The divided regions of the holographic optical element diffract the light beam reflected and diffracted by the optical recording medium, and thereby generate diffraction light beams respectively. The divided regions of the holographic optical element lie in quadrants of an imaginary X-Y coordinate system respectively. An X axis of the coordinate system extends in a direction corresponding to a direction of a pit sequence on the optical recording medium, that is, a tangential direction of the optical recording medium. A Y axis of the coordinate system extends in a direction corresponding to a direction perpendicular to the direction of the pit sequence, that is, a radial direction of the optical recording medium. Photodetectors receive the diffraction light beams generated by the divided regions of the holographic optical element, and convert the received diffraction light beams into corresponding electric signals. Phases of the electric signals are compared, and a tracking error signal is generated on the basis of a result of the phase comparison.
