Patent number: 9448359Abstract: The invention relates to an optical fiber as an optical waveguide for the single-mode operation. The present invention proposes a fiber having a microstructure, by which the propagation of modes of a higher order are selectively suppressed in the optical waveguide. At the same time, the propagation of transversal modes of a higher order is dampened more strongly than the propagation of the fundamental modes of the optical waveguide.Type: GrantFiled: September 21, 2015Date of Patent: September 20, 2016Assignees: Fraunhofer-Gesellschaft zur Foerderung der angewandten Forschung e.V., Friedrich-Schiller-Universitaet JenaInventors: Jens Limpert, Fabian Roeser, Tino Eidam, César Jáuregui Misas, 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
