Abstract: The use of reflecting surfaces that are inclined towards one another enables the multiple reflection of a beam path to be achieved in a laser structure. This permits the realization of compact laser assemblies. The introduction of beam-influencing media between the reflective surfaces or the configuration of said reflective surfaces from or using media of this type allows the use of the multiple reflection for influencing parameters of the radiation or radiation field.

Abstract: 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.

Abstract: Method for processing of material by use of a pulsed laser. Each laser pulse is shaped regarding its beam profile so that a cross sectional area, which is defined by a cross section of the laser pulse in its focal point orthogonal to its propagation direction, is of particular shape and has a main extension axis of greater extent than its minor extension axis. One major crack is effected by each laser pulse, the major crack having a lateral extension basically oriented according to the main extension axis of the respective pulse in the focal point. Furthermore, each laser pulse is emitted so that the orientation of its main extension axis in the focal point corresponds to a pre-defined orientation relative to an orientation of a respective tangent to the processing path at the assigned processing point.

Abstract: In a laser pump arrangement for a laser medium that amplifies a laser beam, comprising at least one laser pump source (1″) with a plurality of emitters for generating partial pumping streams (TPS1″, TPS2″), the partial pumping streams (TPS1″, TPS2″) are led through a coupling optic to a homogenizer (3″) and then are thoroughly mixed in one axis through multiple reflections. In the process, the homogenizer (3″) and the laser medium are designed and disposed such that the pump stream exiting the homogenizer (3″) is led directly onto or into the laser medium while maintaining divergence in the mixing axis (DA), wherein the partial pumping streams (TPS1″, TPS2″) are projected, in particular focused, directly onto or into the laser medium in a projection axis (PA) that is perpendicular to the mixing axis (DA).
