Abstract: The description relates to a device for generating low-divergence laser beams with an optical component divergingly widening the laser beam and a downstream component in the beam path collimating the laser beam. The invention is distinguished in that the component collimating the laser beam is a concave mirror.

Abstract: An argon ion laser has a cathode (2) and an anode (3) at the two ends of its gas-tight discharge tube (1). The anode (3) is designed as a one-piece anode tube (11) made of sintered aluminium oxide powder which does not conduct electricity but is a good conductor of heat; the tube has an electrically conductive inner partial coating (10a). The conductive inner partial coating (10a) acts as an anode electrode and is connected by a solder joint to a flange (7) which serves as an anode lead. The two ends of the tube have a coating (10a, 12), preferably of nickel, which permits gas-tight soldering of the anode tube (11) to both the discharge tube (1) and the flange (7). The flange (7) and the discharge tube (1) are electrically insulated from each other by the anode tube (11). This anode tube (11) can be used to construct a simple and an extremely reliable argon laser; the heat is dissipated from the anode (3) of the laser of the invention much more efficiently than in known lasers because the heat generated at the anode (3) is absorbed directly by the cooling water.

Abstract: Described is a laser whose output power can be varied by means of an adjustment device (45) with an adjustment element (49) which is switched in by the operator but cuts out automatically. Using a beam splitter (15), part of the laser beam (5) is directed on to a light-sensitive element (17) in order to determine the laser power. The values of the selected and instantaneous output power are indicated on the display (32a, 32b) of a display unit (33). The adjustment element (49) can be switched in using only one hand and, with the adjustment element switched in, the laser power required can be adjusted using only one hand.
