摘要： A wavelength-conversion solid-state laser capable of generating a ultraviolet laser beam with high efficiency. The wavelength-conversion solid-state laser is made up of a phonon-based solid-state laser crystal, a semiconductor laser which emanates pump light to pump the phonon-based solid-state laser crystal, a laser resonator, a wavelength selection element which selects an oscillation wavelength, and a nonlinear optical crystal which generates a sum frequency of a solid-state laser beam, whose wavelength is selected by the wavelength-selection element, and the pump light. The phonon-based solid-state laser crystal is pumped with pump light emitted from the semiconductor laser, as a result of which a solid-state laser beam is emitted. A sum frequency of the solid-state laser beam and the pump beam is produced by enabling them to pass through the nonlinear optical crystal.

摘要： A solid-state laser is made up of a solid-state laser crystal, a pump source for pumping the laser crystal, a resonator, an etalon disposed in the resonator for selecting an oscillation wavelength, and a nonlinear optical crystal disposed in the resonator for converting the wavelength of the solid-state laser beam. A wedge-shaped optical member, with two light-transmission end faces being not parallel to each other, is disposed in the resonator. A resonator mode is set to a mode, where the maximum output of a solid-state laser beam is obtained with respect to a resonator temperature in the vicinity of a temperature at which the maximum efficiency of wavelength conversion of the nonlinear optical crystal is obtained, by fixing the wedge-shaped optical member at an optimum position. A wedge-shaped nonlinear optical member may be used both as the nonlinear optical crystal and the wedge-shaped optical member, or a wedge-shaped etalon may be used both as the etalon and the wedge-shaped optical member. Alternately, the solid-state laser further includes a wedge-shaped birefringent polarization control element, with two end faces being not parallel to each other, for controlling the direction of linear polarization of a solid-state laser, and this wedge-shaped birefringent polarization control element may be used as the wedge-shaped optical member.

摘要： In a laser diode pumped solid state laser, a primary solid state laser medium containing a rare earth metal is pumped by a semiconductor laser, and the wavelength of a laser beam having been obtained from the solid state laser oscillation is converted by a nonlinear optical material into a different wavelength.

The solid state laser medium for injection locking is pumped by the semiconductor laser and produces a laser beam for injection locking through solid state laser oscillation in a single longitudinal mode, such that the laser beam for injection locking may impinge upon the primary solid state laser medium.
