摘要： Kinematic mounts have three points having zero degree of freedom, one degree of freedom, and two degrees of freedom, respectively. As viewed from a direction perpendicular to a plane containing the three points, an extension of an entrance optical axis of a laser beam to an amplifying apparatus or an extension of an exit optical axis from the amplifying apparatus is oriented to the point with the zero degree of freedom. A translational direction of the point with the one degree of freedom is oriented to the point with the zero degree of freedom. One of the extension of the entrance optical axis and the extension of the exist optical axis passes on a side closer to the point with the two degrees of freedom with respect to a side of the point with the one degree of freedom.

摘要： A gas laser device includes a housing for enclosing a laser gas. The housing includes a main body having a frame-like structure with openings formed on both sides thereof, and a pair of cover members detachably attached to cover each of the openings. The main body is provided with an upper plate and a lower plate each extending along the optical axis of the laser light, and a pair of side plates respectively connecting both ends of the upper plate and the lower plate. Each of the cover members includes a partially cylindrical member having an arc-like cross-sectional shape in a plane perpendicular to the optical axis and extending along the optical axis, and a pair of side wall members occluding both ends of the partially cylindrical member. The partially cylindrical member has a bellows portion molded into a shape having peaks and valleys each alternating along the optical axis.
