    Abstract: A solid state laser capable of cooling a solid state laser medium to have a uniform temperature along the propagating direction of a light to be amplified. Since cooling water flowing through channels (12a, 12b) is brought into direct contact with a pair of reflective end faces (5a, 5b) of the solid state laser medium (3) in the solid state laser (1), the laser medium (3) heated by excitation light emitted from a semiconductor laser (9) can be cooled efficiently. Since the cooling water flows through the channels (12a, 12b) in the direction substantially perpendicular to the propagation plane P of the light L to be amplified, the solid state laser medium (3) can be cooled to have a uniform temperature along the propagating direction of the light L to be amplified. Consequently, thermal lens effect and thermal double refraction effect can be reduced in the solid state laser medium (3).

    Abstract: Provided is a laser device including N semiconductor laser array stacks, a prismatic optical system that shifts optical axes of luminous fluxes respectively output from the N semiconductor laser array stacks so as to decrease intervals among the luminous fluxes, and an imaging optical system that causes the luminous fluxes to be condensed and deflected for each luminous flux. The imaging optical system causes the luminous fluxes to be deflected so that the luminous fluxes overlap each other at a predetermined position and generates a light-condensing point of the luminous fluxes between the imaging optical system and the predetermined position.

    Abstract: A laser device 1 demultiplexes seed light L 0 into a plurality of beams of laser light L 1 and then continuously optically amplifies the plurality of beams of the laser light L 1 with an amplifier 14. Therefore, its amplification factor can be set higher than that in the case of amplifying pulsed laser light. When producing multiplexed light L 3 by multiplexing the beams of the amplified laser light L 1 with a diffraction grating 16, respective phases of the beams of the laser light L 1 are controlled such that an output peak of the multiplexed light L 3 repeatedly appears at a converging position P 1 at a predetermined time interval. This produces pulsed laser light at the converging position P 1 from a plurality of beams of laser light L 2 amplified at a high amplification factor. Hence, this laser device 1 can produce pulsed laser light with a high output.

    Abstract: PROBLEM TO BE SOLVED: To provide a laser apparatus suitable to the driver for a laser nuclear fusion reactor.
    SOLUTION: In the laser apparatus 1, an equilateral polygon along which laser-beam incident/outgoing surfaces 18a of laser media 18 are arranged includes n sides. When a laser beam performs its incidence on the k-th laser medium 18 counted from the laser medium 18 wherefrom the laser beam has gone out, the incident angle θ (degree) of the laser beam on the laser-beam incident/outgoing surface 18a of the k-th laser beam medium 18 satisfies the relational expression of 0.9×90×(n-2k)/n≤θ≤1.1×90×(n-2k)/n, wherein n/k is not an integer and (the least common multiple of n and k)≥n×k is existent in the case of [n>3, k≥1], [k 1]. Thereby, all the laser media 18 are so used as to be able to make the laser beam come and go among the laser media 18 and amplify and output the laser beam.
