摘要： A solid-state light source apparatus includes a first excitation laser light source for outputting a laser beam of a first wavelength, a second excitation laser light source for outputting a laser beam of a second wavelength, a difference frequency between the laser beam of the first wavelength and the laser beam of the second wavelength being in a terahertz band, and a semiconductor pseudo phase matching device which is disposed at a place where a first optical axis of the laser beam of the first wavelength overlaps with a second optical axis of the laser beam of the second wavelength, and generates a terahertz beam in a direction coaxial with the first and second optical axes on the basis of irradiation of the laser beams of the first and second wavelengths. Thus, high output and high efficiency terahertz wave generation can be easily and certainly realized while a narrow line width characteristic is maintained.

摘要： A planar waveguide laser device forms a waveguide by a plate-like laser medium (1) having birefringence and clad (2a, 2b) attached to at least one of the surfaces of the laser medium (1) perpendicular to its thickness direction, amplifies laser light by a gain produced by excitation light incident on the laser medium (1), and performs laser oscillation. The laser medium (1) is formed of a material having an optic axis on a cross section perpendicular to the light axis, which is the laser travelling direction. The clad (2a, 2b) is formed of a material having a refractive index in a range between refractive indexes of two polarized lights that travel along the light axis in the laser medium (1) and have oscillation surfaces that are orthogonal to each other. The planar waveguide laser device readily oscillates linearly polarized laser light.

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.

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.
