    摘要: A fibre laser comprises a fibre light guide (3) having an active medium, a laser as pumping source (1) and a first pair of Bragg gratings (6, 8) forming a first resonator (4). The first pair of Bragg gratings (6, 8) resonates the pump laser (1) and there is provided a second pair of Bragg gratings (7, 9) resonating at the output wavelength of the fibre laser.

    摘要: A rolling mill stand with at least one manipulator for axially moving the rolls, particularly the work rolls, of the rolling mill stand. The rolls are supported and secured in chocks. The chocks are guided in the housings of the rolling mill stand so as to be vertically slidable in the direction of the rolling force. The chocks include pushing blocks which guide horizontally in the direction of the rolling axes. The manipulators supported by the housings act on the pushing blocks from the operator side. The manipulator is connected to the pushing block through a gear arrangement for transmitting the adjusting distance of the manipulator. The gear arrangement operates without slipping.
