    摘要： The invention relates to a marking apparatus (100) for marking an object with laser light, comprising a plurality of gas lasers (10) and a control unit for individually activating each of the gas lasers (10) to emit a laser beam according to a sign to be marked. The gas lasers (10) are stacked such that the laser beams emitted by the gas lasers (10) form an array of laser beams, in particular a linear array with parallel laser beams, each gas laser (10a-i) comprises laser tubes (12) that at least partially surround an inner area (5). The apparatus (100) further comprises beam-delivery means (14) for directing the array of laser beams into the inner area (5) and a set of deflection means (30) for rearranging the array of laser beams into a desired array of laser beams. The set of deflection means (30) is arranged in the inner area (5) and comprises at least one deflection means (33a, 33i) per laser beam, in particular at least one mapping mirror (33a, 33i) or one optical waveguide per laser beam. Each deflection means (30) is individually adjustable in its deflection direction and/or individually shiftable.

    摘要： A ring laser gyroscope comprises a laser block that defines an optical closed loop pathway configured to contain a lasing gas. A plurality of mirror structures are respectively mounted on the laser block, with each of the mirror structures having a respective reflective surface that is in optical communication with the optical closed loop pathway. A plurality of electrodes are coupled to the laser block, with the electrodes configured to generate a pair of counter-propagating laser beams from the lasing gas in the optical closed loop pathway. At least one optical sensor is coupled to one of the mirror structures, with the optical sensor in optical communication with the closed loop pathway. A polarizer is in optical communication with the optical sensor. The polarizer is configured to pass laser light having substantially one polarization mode to the optical sensor.

    摘要： A laser oscillator which can keep distributions of pressure of a laser medium inside of a plurality of discharge tubes constant while making the laser medium circulate without stagnating. The laser oscillator is comprised of a first discharge tube, second discharge tube, first light guide, laser medium flow path, and blower. A flow resistance of a laser medium flow path between the blower and the first discharge tube and a flow resistance of the laser medium flow path between the blower and second discharge tube are the same as each other. A flow resistance of the laser medium flow path between the blower and a first end of the first light guide and a flow resistance of the laser medium flow path between the blower and a second end of the first light guide differ from each other.
