20130114631 | VALVE FOR THE SUBSTANTIALLY GAS-TIGHT INTERRUPTION OF A FLOW PATH - The invention relates to a mirror arrangement for guiding a laser beam in a laser system having at least one first end mirror and one second end mirror, wherein said end mirrors define a resonator having an optical resonator axis, wherein the laser beam is guided into the resonator as an input laser beam and is guided out of the resonator again after multiple reflection at the first and second end mirrors as an output laser beam. The sequence of reflections at the first and second end mirror thereby determines a direction of rotation between the first and second end mirror, defined as an axis of rotation relative to the resonator axis, whereby a first beam path is defined and the laser beam circulates in a direction of rotation between the first and second end mirrors in the resonator defined as an axis of rotation relative to the resonator axis. The resonator is designed such that the direction of rotation is reversed at a reversing point and the laser beam in the resonator passes through at least partially in a direction of rotation opposite to the first beam path, whereby a second beam path is defined. | 05-09-2013 |
20130089119 | LASER COMPRISING A LASER MEDIUM - A laser having a standing wave resonator including a first resonator section, which has at least a first end mirror and a second resonator section, which has at least a second end mirror. At least one of the optical elements of the first resonator section is embodied in focusing fashion. Accordingly, the beam axes of the laser beam which arrives upon respective tiltings of at least one of the optical elements in the second resonator section have at least one crossing point, which lies in the pump region of the laser medium or is at a distance from the pump region which amounts to less than the Rayleigh length. The radius (w) of the laser beam is less than five times the radius (w) of the laser beam in the pump region of the laser medium. | 04-11-2013 |
20120300799 | LASER AMPLIFICATION SYSTEM AND METHOD FOR GENERATING RETRIEVABLE LASER PULSES - The invention relates to a laser amplification system for generating retrievable laser pulses having at least one laser source, in particular with a pulse selector arranged downstream thereof for the targeted selection of amplifiable laser pulses, a laser medium for amplifying laser pulses generated by the laser source and a loss modulator, wherein the loss modulator is arranged and connected such that said modulator modulates the amplification of the laser pulses by the laser medium by loss generation so that the retrievable laser pulses are provided with a predefined pulse time and/or pulse energy. Before an amplification process for one of the laser pulses, the current amplification of the laser medium is determined and the loss generation is controlled by the loss modulator depending on the current amplification of the laser medium. | 11-29-2012 |
