摘要： A diode laser array containing a plurality of electrically series-connected diode lasers (2) to which a bypass device (4) is respectively electrically and parallel connected. Said device is high-ohmic in normal operation and bypasses the respective diode laser (2) in the case of a diode laser diode defect leading to high-ohmic interruption of the electric circuit.

摘要： The invention relates to an optically pumped solid state laser comprising a laser medium (1) that is surrounded by a pump-beam reflector (7), which has at least one opening (8) for coupling the pump beam (14) that is emitted from a pump-beam source (9) into the pump-beam reflector (7). A beam guidance lens or beam shaping lens (10, 11; 11a-i) is located between the pump-beam source (9) and the laser medium (1). Said lens comprises at least one optical element (11; 11a-i), which is positioned in the beam path of the pump-beam source (9) inside the pump-beam reflector (7). The optical element (11; 11a-i) modifies at least one part of the pump beam (14), which is directly oriented towards the laser medium (1), with regard to its power density distribution.

摘要： According to the invention, the proposed laser welding head comprises a housing (2) in which are arranged an outlet aperture for a focused laser beam (6) and a flow duct (8) within the housing which runs past the outlet aperture (4) and carries a laminar gas flow (12) in the region of the outlet aperture (4). These features facilitate particularly efficient deviation of the molten material droplets thrown up during welding from the welded region towards the optical focusing system and thereby prevent fouling of the said optical system. The speed of the laminar gas flow in the region of the outlet aperture (4) will be preferably about 90 % of the speed of sound.
