Abstract:
PCT No. PCT/EP90/00693 Sec. 371 Date Oct. 31, 1991 Sec. 102(e) Date Oct. 31, 1991 PCT Filed Apr. 30, 1990 PCT Pub. No. WO90/13930 PCT Pub. Date Nov. 15, 1990.A solid state type laser contains a laser rod (1) and at least one pumping module (2d, 2e) equipped with laser diodes (D) which is designed as a ring-shaped or partial ring-shaped module with a circumferential cooling duct (4). This geometry permits the lost heat of the laser diodes (D) to be effectively removed radially outward through the cooling duct (4), on the one hand, and through thermal conduction in the material of the module, on the other hand. The individual laser diodes are so arranged that the major axis of each rotationally non-symmetrical lobe of laser light, along which axis the main radiation power from the respective laser diode is obtained, lies in a plane substantially parallel to the longitudinal axis of the laser rod.
