Abstract
A modular CO2 laser has two end-flange devices, at least one intermediate-flange device, at least one metallic support tube that is resistant to bending and has two end regions fixedly mounted in the two end-flange devices and a central region to which the intermediate-flange device is secured. A partially-transmitting mirror device is provided at at least one of the end-flange devices, the mirror device comprising a mirror and a massive support plate carrying a mounting for the mirror. An adjusting-screw device is provided, which comprises a reference position forming an origin of X axis and Y axis coordinates. Two metal screws are situated in the X axis and Y axis respectively, the mirror being adjustable by rotation of at least one of the screws. The metal of the metallic support tube has a coefficient of thermal expansion that is not particularly low, and the metal of the metal screws has a particulary low coefficient of thermal expansion.
