Patent number: 9484709Abstract: The invention relates to an optical amplifier arrangement for amplifying ultra-short pulsed laser radiation comprising a mode-locked laser (1) and two or more optical amplifiers (3) arranged downstream of the laser (1) in the propagation direction of the laser radiation. Optical amplifier arrangements of this type are known in the prior art. Here the intention is to present an alternative to the known amplifier arrangements. The invention proposes arranging between the laser (1) and the optical amplifiers (3) at least one splitting element (2) which splits the pulsed laser radiation between a plurality of amplifier channels (4), wherein each amplifier channel (4) has at least one optical amplifier (3), and wherein at least one common combination element (5) is disposed downstream of the amplifier channels (4) and coherently superimposes the pulsed laser radiation amplified in the amplifier channels (4).Type: GrantFiled: August 29, 2011Date of Patent: November 1, 2016Assignees: FRAUNHOFER-GESELLSCHAFT ZUR FOERDERUNG DER ANGEWANDTEN FORSCHUNG E.V., FRIEDRICH-SCHILLER-UNIVERSITAET JENAInventors: Arno Klenke, Enrico Seise, Jens Limpert, Andreas Tuennermann

Patent number: 8982453Abstract: The invention relates to a laser device (1) for amplifying and/or transporting electromagnetic radiation, comprising a radiation source (2) for generating the electromagnetic radiation and an amplifier (4) for amplifying or a medium for transporting the generated electromagnetic radiation. In order to make available a device (1) for amplifying or transporting electromagnetic radiation that provides a very easy to implement possibility for reducing the influence of non-linear effects, the electromagnetic radiation propagating in the amplifier (4) or medium is largely non-linearly polarized.Type: GrantFiled: July 9, 2010Date of Patent: March 17, 2015Assignees: Fraunhofer-Gesellschaft zur Foerderung der Angewandten Forschung E.V., Friedrich-Schiller-Universitaet JenaInventors: Jens Limpert, Andreas Tuennermann, Damian Schimpf, Tino Eidam, Enrico Seise, Fabian Roeser

Patent number: 8760753Abstract: The present invention relates to a device (12) and to a method for amplifying light impulses (13). The device comprises a stretcher (15) stretching the light impulses over time, at least one amplifier (16) amplifying the stretched light impulses, and a compressor (17) compressing the stretched and amplified light impulses, wherein the amplifier (16) applies a non-linear phase generated by self-phase modulation to the stretched light impulses. In order to provide a device and a method for amplifying light impulses, by means of which light impulses having higher light impulse quality and light impulse peak power can be generated, the invention proposes that means for spectrally shaping the light impulses are disposed ahead of the amplifier (16) in the beam path, wherein the means for spectrally shaping the light impulses bring about a spectral trimming of the light impulses.Type: GrantFiled: December 23, 2009Date of Patent: June 24, 2014Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V., Friedrich-Schiller-Universitaet JenaInventors: Jens Limpert, Enrico Seise, Damian Schimpf, Fabian Roeser, Andreas Tuennermann
