Abstract: A laser light beam generating apparatus includes at least one light beam source (71), first (76) and second (77) reflectors, a non-linear optical crystal element (78) and an electromagnetic actuator (79). The light beam source (71) emits a light beam. The non-linear optical crystal element (78) is provided between the first reflector (76) and the second reflector (77). A light beam emitted from the light beam source (71) is incident on the non-linear optical crystal element (78) through the first reflector (76) and the second harmonic thereof is generated. The actuator actuates at least one of the first (76) and second (77) reflectors along an optical axis of the light beam emitted from the light beam source (71).

Abstract: A laser beam generator (13) includes first and second mirrors (14R, 16R), a laser light source (11), a laser medium (15), a non-linear optical crystal element (16) and a birefringent element (14). The laser light source generates a pumping light beam. The laser medium (15), arranged between the first and second mirrors (14R, 16R) is irradiated with the pumping light beam via one of the mirrors (14R) to generate a fundamental laser beam based on the pumping light beam. The non-linear optical crystal element (16) is arranged between the first and second mirrors to generate a second harmonic laser beam under the type II phase matching as the fundamental laser beam from the laser medium (15) is passed through it in resonant oscillation. The birefringent element (14) has its one surface at a pumping light beam inlet side coated with a high reflectance coating (14R) and has its opposite surface parallel to it with a nonreflective coating (14T). The birefringent element (14) is set so that its optical axis is inclined at a predetermined azimuth angle with respect to the crystal axis of the non-linear optical crystal element (16). The surface of the birefringent element (14) coated with a high reflectance coating (14R) constitutes one of the first or second mirrors.

Abstract: A system for correcting for positional deviations in a hand-held video camera caused by small movements or shaping of the user's hands includes an afocal optical system constituted by a positive meniscus lens and a negative meniscus lens. The positional deviations of the camera caused by minute tremors or shaking of the user's hands are detected by a pitch sensor and a roll sensor and micro-computer is responsive to the detected amount of the positional deviations to drive the positive meniscus lens and the negative meniscus lens in vertical and horizontal directions with respect to the optical axis, thereby controlling the position of the image pickup light being radiated onto a CCD image sensor of the video camera.

Abstract: In a laser beam generator for making wavelength conversion with an automatic control of the length of an external resonator (3) or the resonator of the laser souce (6), for achieving a high efficiency wavelength conversion, the servo pulling-in is performed by use of the resonator length error signal and the reflected light signal. A sample-and-hold means is used to detect the error signal from the detected light signal which is reflected from the external resonator.

Abstract: A laser light source (21A - 21N) in which a couple of light beams (LA, LB) whose shapes are re-formed and whose polarizing planes are made perpendicular to each other are synthesized by a beam splitter (32) and then the synthesized light is incident on an optical guide through a predetermined optical system, thereby generating the synthesized light (LL) having a short spot diameter and an improved power density.
