摘要： Laser devices include a light source that emits a laser beam, an optical system that concentrates the laser beam emitted from the light source, an optical window through which the laser beam exited from the optical system passes, a housing that accommodates the optical system, and an optical window holding member fixed to the housing. The optical window holding member holds the optical window. In the first laser device, the optical window has a face or a protruding face through which the laser beam passes. When the optical window has the face, the face is flush with an edge of the optical window holding member and a film is formed on the face. When the optical window has the protruding face, the protruding face protrudes with reference to the edge of the optical window holding member and a film is formed on the protruding face.
