Abstract
The disclosure relates to an optical system comprising a laser source () which generates pulsed laser radiation consisting of a temporal sequence of laser pulses in an input laser beam (EL), a splitting element () which follows the laser source () 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 () which follows the splitting element () 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. The disclosure proposes that at least one multipass cell () is arranged in the beam path between the splitting element () and the combination element (), through which the laser pulse replicas propagate, wherein the multipass cell () contains a medium in which the laser pulse replicas undergo nonlinear spectral broadening.
