摘要： A laser device includes a support, a first heat sink, a plurality of laser light sources attached to the support, and a plurality of electrodes bridged between the plurality of laser light sources and the first heat sink. Each of the plurality of laser light sources is movable with respect to the support. Each of the plurality of electrodes is electrically connected to one of the plurality of laser light sources at a first connection portion, and is thermally connected to the first heat sink at a second connection portion. In each of the plurality of electrodes, an extension part between the first connection portion and the second connection portion has flexibility, and a length of the extension part is larger than a linear distance between the first connection portion and the second connection portion.

摘要： Disclosed is a laser medium unit that includes a laser medium and a holding body. The laser medium has a pair of end surfaces. The holding body surrounds the laser medium when viewed form a direction intersecting with the pair of end surfaces and holds the laser medium. The holding body includes a deformation allowing portion that extends from the inside to the outside of the holding body when viewed from the direction intersecting with the pair of end surfaces. The laser medium and the holding body are in contact with each other. A contact region of the holding body with the laser medium has a width in the direction intersecting with the pair of end surfaces and extends along a side surface of the laser medium when viewed from the direction intersecting with the pair of end surfaces.

摘要： An optical amplification device includes: a laser medium that amplifies input light to generate output light; an excitation light source that supplies excitation light used for amplifying the input light, to the laser medium; a resonator that includes a pair of first optical elements and disposed to optically face each other with the laser medium interposed between the first optical elements and that resonates generated light generated in the laser medium through the supply of the excitation light; and an optical switch disposed on an optical path of the resonator between the pair of first optical elements.
