APPARATUS FOR THE SPECTRAL BROADENING OF LASER PULSES AND OPTICAL SYSTEM

摘要

The invention relates to an apparatus (1) for the spectral broadening of laser pulses (2), comprising: a plurality of mirror elements (6), on each of which a mirror surface (6b) for reflecting laser pulses (2) is formed, wherein the plurality of mirror elements (6) is fixed to a main part (4a), and at least one, preferably planar, in particular disc-like, non-linear, optical solid state medium (10) and/or at least one gaseous, non-linear, optical medium for passage of the laser pulses (2) for the generation of a non-linear phase (ΦΝL) by self-phase modulation. The invention also relates to an optical system, comprising: a radiation source for generating laser pulses (2), an apparatus (1) for the spectral broadening of the laser pulses (2), which apparatus is designed as described above, and an apparatus for the temporal compression of the spectrally broadened laser pulses.
