Abstract
A laser machine tool includes a laser beam generator (3) and a machining head (5), and the laser beam (2) passes between the laser beam generator (3) and the machining head (5) in a beam passage (25) that is at least partially closed. The beam passage (4) is filled with air with a limited CO.sub.2 content. In this way, the laser beam (2) in the beam passage is protected at low cost from the influence of gases that reduce its power, especially when the path of the beam is very long.
