    摘要： A gas laser device which can perform optical amplification, laser light passing through a laser gas excited by electrical discharge, including: a first and second pair of discharge electrodes arranged longitudinally along an optical axis of the laser light; at least two mirrors reflecting the laser light amplified by the gas laser, the mirrors arranged opposite to each other to interpose a first discharge region defined by the first pair of discharge electrodes and a second discharge region defined by the second pair of discharge electrodes therebetween; and a shielding member located between the first pair of discharge electrodes and the second pair of discharge electrodes, the shielding member protruding from electrode surfaces of the discharge electrodes toward the optical axis of the laser light. The configuration can efficiently suppress parasitic oscillation with a simple structure.

    摘要： A radio frequency (RF) excited laser assembly includes a pair of opposed electrodes defining an inter-electrode gap and a conductive termination bridge in electrical contact with both electrodes. The termination bridge mechanically supports and positions the electrodes relative to each other and provides a termination impedance for an RF voltage applied to the electrodes. A conical spiral inductor includes one or more metals windings, and one or more concentric terminals, such that the conical spiral inductor defines an inter-winding spacing sufficient to mitigate ionization of a gas medium between windings. A radio frequency (RF) feed-through assembly configured to apply an RF voltage to a pair of opposing electrodes such that a conductor is isolated from a metal sleeve position around the conductor by ion sheath discharge barrier.

    摘要： A CO2 gas laser device according to the present invention amplifies CO2 laser light that oscillates repeatedly in short pulses having a pulse width of 100 ns or less, and cools a CO2 laser gas which is excited by continuous discharge by circulating the CO2 laser gas by means of forced convection. Therein, an angle θ defined by the optical axis of the amplified CO2 laser beam and the flow direction of the CO2 laser gas caused by the forced convection is determined by both a discharge cross sectional area and a discharge length of a volume in which the CO2 laser gas is excited by discharge, whereby increasing the gain of pulsed laser to achieve pulsed laser light having an extremely high average output power.

    摘要： An apparatus includes a first plurality of concave reflecting surfaces; a second plurality of reflecting surfaces facing the first plurality of concave reflecting surfaces such that a region is defined between the first and second pluralities; and an input for an optical beam to enter the region and an output for the optical beam to exit the region. The first and second pluralities of reflecting surfaces are arranged relative to each other so that the optical beam is re-imaged at a reflecting surface of one of the pluralities after only one reflection from a reflecting surface of the other of the pluralities and so that overlap of two or more optical beams on each of the reflecting surfaces is avoided.

    摘要： A CO2 gas flow laser with multiple discharge modules places acoustic baffles between the discharge modules to suppress shock waves and ions passing between the discharge modules such as may disrupt the optical path of the laser. A catalyst may be placed in a center of a toroidal recirculation chamber of the laser and may have integrated filters to prevent catalyst particulates from coating the chamber optical windows.

The laser system includes a laser oscillator for generating a pulse laser beam by laser oscillation, plural amplifiers for sequentially inputting the pulse laser beam generated by the laser oscillator and amplifying the pulse laser beam, and a control unit for controlling the laser oscillator to perform burst oscillation and halting an amplification operation of at least one of the plural amplifiers in a burst halt period between burst oscillation periods.
