摘要： A solid-state laser rod pumping module has a stack-type semiconductor laser including a plurality of bar-shaped components that are stacked in a direction parallel to the axis of a solid-state laser rod. Each bar-shaped component includes a plurality of laser-light-emitting portions that are aligned and integrated in a direction orthogonal to the axis of the solid-state laser rod. The large divergence angle of the stack-type semiconductor can be compensated by including a light focusing component for focusing laser light emitted out of the stack-type semiconductor laser. The focused light is guided by a laser light guiding component disposed in a diffusive reflection tube. A light guiding component guides the focused light onto a solid-state laser rod located within the diffusive reflective tube, while maintaining the length of one side of the cross section of the guided light.

摘要： A solid-state laser oscillator comprising solid-state laser rods disposed coaxially in series with each other, radiating light when excited, and amplifying the light through stimulated emission. A solid-state laser rod exciting device excites any number of solid-state laser rods with a 90° optical rotator disposed coaxially and arranged between the rods. The rotator rotates a component of the light generated in the axial direction while heat lens compensating devices are disposed coaxially with the solid-state laser rods. A reflecting device and a partial reflection device are disposed coaxially and arranged, outside of the solid-state laser rods and heat lens compensating devices, for propagating the axially generated component of the light. An exciting source driving device drives the exciting sources included in the solid-state laser rod exciting device.

摘要： A plane waveguide type laser according to the present invention includes: a plate-shaped laser medium (5); a semiconductor laser (1) which causes excitation light to enter an end surface (5a) of the laser medium (5); first and second claddings (4a and 4b) which are bonded to lower and upper surfaces of the laser medium (5), respectively, to form a waveguide in a vertical direction; a comb heat sink (2) bonded to a lower surface of the first cladding (4a); and thermal lens producing means (20) bonded to an upper surface of the second cladding (4b). In this structure, laser oscillation in the vertical direction is performed in a waveguide mode of the laser medium (5), and the thermal lens producing means (20) forms a periodic lens effect in the laser medium (5) to perform laser oscillation in a lateral direction in a plurality of resonant modes. Therefore, a resonator having a small round-trip loss maybe formed without depending on a size of a thermal lens produced by excitation, and hence a rising characteristic of a pulse operation or a CW operation may be smoothed to obtain high-power stable output.

摘要： In a laser device, a control range of focal distance of a generated thermal lens is broadened and reliability is improved. A mode control waveguide-type laser device includes: a planar laser medium having a waveguide structure in a thickness direction of a cross section perpendicular to an optical axis, for generating gain with respect to laser light; a cladding bonded onto the laser medium; and a heat sink bonded onto the laser medium. The laser medium generates a lens effect, and the laser light oscillates in a waveguide mode in the thickness direction, and oscillates in a spatial mode due to the lens effect in a direction perpendicular to the optical axis and the thickness direction. The refractive index distribution within the laser medium is created by generating a temperature distribution in the laser medium depending on a junction area of the cladding and the heat sink.
