Publication number: 20230335964Abstract: The invention relates to an optical system comprising: a laser source which generates pulsed laser radiation consisting of a temporal sequence of laser pulses; and at least one pulse compression device which is located in the beam path and has a non-linear medium, wherein the laser pulses undergo non-linear spectral broadening during propagation through the medium, and a chirp is applied to the laser pulses. The aim of the invention is to provide an optical system which makes it possible to generate non-linearly compressed laser pulses with improved temporal pulse contrast or with improved pulse quality. According to the disclosed approach, a group delay dispersion which varies along the beam path and which compensates at least partially for the chirp is applied to the laser pulses by the pulse compression device.Type: ApplicationFiled: August 5, 2021Publication date: October 19, 2023Applicant: Active Fiber Systems GmbHInventors: Tino EIDAM, Christian GAIDA, Steffen HÄDRICH, Fabian STUTZKI

Publication number: 20230275385Abstract: The disclosure relates to an optical system comprising a laser source (1) which generates pulsed laser radiation consisting of a temporal sequence of laser pulses in an input laser beam (EL), a splitting element (2) which follows the laser source (1) in the course of the beam and splits each of the laser pulses into laser pulse replicas separated spatially and/or temporally from one another, a combination element (4) which follows the splitting element (2) in the course of the beam and superimposes the laser pulse replicas in a respective laser pulse in an output laser beam. It is the task of the disclosure to provide an improved optical system compared to the prior art. It should be possible to generate particularly short and thus spectrally broadband laser pulses of high power with the optical system.Type: ApplicationFiled: June 14, 2021Publication date: August 31, 2023Applicant: Active Fiber Systems GmbHInventors: Tino EIDAM, Steffen HÄDRICH, Fabian STUTZKI

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: 9235106Abstract: The invention relates to a method and corresponding devices for reducing mode instability in an optical waveguide (1), a light signal becoming unstable in the optical waveguide (1) beyond an output power threshold and energy being transformed from a basic mode into higher order modes. The invention proposes a reduction in temperature variation (2) along the optical waveguide (1) and/or a reduction in changes in the optical waveguide (1) that are caused by spatial temperature variation as a result of mode interference.Type: GrantFiled: April 12, 2013Date of Patent: January 12, 2016Assignees: FRAUNHOFER-GESELLSCHAFT ZUR FÖRDERUNG DER ANGEWANDTEN FORSCHUNG e.V., FRIEDRICH-SCHILLER-UNIVERSITÄT JENAInventors: César Jáuregui Misas, Hans-Jürgen Otto, Fabian Stutzki, Florian Jansen, Tino Eidam, Jens Limpert, Andreas Tünnermann

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
