20120033704 | LASER PUMP ARRANGEMENT AND LASER PUMP METHOD WITH BEAM HOMOGENIZATION - In a laser pump arrangement for a laser medium that amplifies a laser beam, comprising at least one laser pump source ( | 02-09-2012 |
20110032968 | Laser arrangement and resonator element for such a laser arrangement - In a laser arrangement comprising at least one laser medium for producing a laser emission, a laser resonator having a beam path with a length of at least 20 cm and with at least one end mirror, the beam path within the laser resonator is formed at least partly by free-beam optics. A resonator element arranged in the beam path has at least two optical surfaces as surfaces interacting with the radiation led via the beam path, these optical surfaces being rigidly connected to one another and being adjustable together in the beam path in such a way that, on tilting by an angle error, they achieve substantially the same effect on the guidance of the beam path but with opposite sign, so that mutual compensation of tilt errors takes place. | 02-10-2011 |
20100303106 | Ultra-short pulse laser system and method for producing femtosecond or picosecond pulses - An ultra-short pulse laser system comprising an amplifying laser medium for producing a laser emission, a laser resonator having at least one resonator mirror and a pump source has a gas-filled section with a filling gas, the latter consisting of a single gas or a filling gas mixture differing from the composition of air, whose nonlinear refractive index n | 12-02-2010 |
20100272137 | LASER AMPLIFIER SYSTEM AND LASER AMPLIFIER METHOD - A laser amplification arrangement comprising a laser medium for producing an amplified laser emission as output signal from a useful signal to be amplified and a pump source has a switching component for coupling the useful signal into the laser medium. Laser medium and switching component are formed and arranged so that a division of an input signal (ES) into the useful signal and a background signal is effected, the background signal being passed through the laser medium at a time immediately before and/or after the coupling-in of the useful signal to be amplified. | 10-28-2010 |
