摘要： PROBLEM TO BE SOLVED: To provide a multi-beam coupling device capable of controlling the respective phases of a plurality of laser beams with a simple configuration.SOLUTION: The multi-beam coupling device comprises: a phase shift part; a superimposing part; an observation part; and a phase control part. The phase shift part generates a plurality of shifted laser beams by shifting respective phases of the plurality of laser beams. The superimposing part generates a plurality of overlapped laser beams by superimposing the plurality of shifted laser beams on a reference beam. The observation part generates interference pattern information on a spatial interference pattern that appears when each of the superimposed laser beams is observed. A phase control part feedback-controls phase shifting by the phase shift part on the basis of interference pattern information obtained for each superimposed laser beam to thereby set the plurality of shifted laser beams into a desired state.
摘要翻译：要解决的问题：提供能够以简单的结构控制多个激光束的各个相位的多光束耦合装置。解决方案：多光束耦合装置包括：相移部分; 叠加部分; 观察部分; 和相位控制部。相移部分通过移动多个激光束的各个相位来产生多个移动的激光束。叠加部分通过将多个移动的激光束叠加在参考光束上来产生多个重叠的激光束。观察部分产生当观察到每个叠加的激光束时出现的空间干涉图案上的干涉图案信息。相位控制部分基于针对每个叠加的激光束获得的干涉图案信息反馈控制由相移部分的相移，从而将多个移动的激光束设置为期望的状态。

摘要： PROBLEM TO BE SOLVED: To generate a high quality laser beam by controlling an adverse effect of heat generated from a gain medium. SOLUTION: The laser gain medium includes an optical medium which transmits a laser beam and has an incidence plane, a first surface, and a second surface facing the first surface. A plurality of first surface side gain media which amplify the laser beam are bonded to the first surface of the optical medium. At least one second surface side gain medium which amplifies the laser beam is bonded to the second surface of the optical medium. A plurality of first reflecting surfaces, i.e. the surfaces of the plurality of first surface side gain media facing the first surface, and a second reflecting surface, i.e. the surface of the second surface side gain medium facing the second surface, form the optical path of pumping light which enters at a predetermined angle from the incidence plane and travels zigzag. The gain medium is divided into a plurality of sections, thereby a large gain can be achieved by multistage amplification and heat generated in the gain medium can be distributed and controlled.

摘要： 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.
