レーザ装置。 It is equipped with a cylindrical lamp and a cylindrical condensing tube that is arranged in parallel with a cylindrical solid-state laser material with approximately the same diameter as the lamp, and further surrounds them to focus the light from the lamp onto the laser material. In a solid-state laser device, when viewed in a cross section perpendicular to the central axis of the lamp or the central axis of the laser material, the shape of the condenser tube is a shortening of two ellipses with the same minor axis radius and different major axis radius. It is a shape in which the two types of semi-ellipses are cut in half along the axis and pasted together along the short axis, and the focal positions of the two types of ellipses are at the cross-section of the lamp and the cross-section of the laser material. A solid-state laser device characterized by using a condensing tube that can be inserted into the tube.
