Abstract: A laser comprises an active element and two resonators wherein each resonator further comprises a highly reflective resonator element and an output coupling element which reflects the radiation of the active element in itself. The active element amplifies incident radiation from a solid angle range by a normal of the active element which is distinctly greater than zero. The resonators are arranged relative to the active element such that each resonator reflects the radiation on the active element at a different angle of incidence within the solid angle range.

Abstract: 0587788986 The arrangement for combining and shaping the radiation of a plurality of laser diode lines, comprising at least two laser diode lines whose radiation has a cross section in the emission plane (x-y plane) whose longitudinal axis is a multiple of the transverse axis, one collimator unit for each laser diode line, which collimator unit is arranged downstream thereof in the radiation directly, a combining unit for combining the collimated radiation of the individual laser diode lines by a side-by-side arrangement in the direction of the transverse axis, and a recombining unit for dividing the combined radiation in the direction of the longitudinal axes into individual partial beams and recombining the latter by a side-by-side arrangement in the direction of the transverse axes.
