Abstract: An apparatus for beam shaping of laser radiation in the form of ultra short pulses includes an achromatic optical device comprising a first substrate having a first Abbe number and a second substrate connected to the first substrate and having a second Abbe number that is different from the first Abbe number. The first and second substrates are arranged to allow the laser radiation to at least partially pass through the first and second substrates in succession, wherein an optically functional transformation boundary surface is disposed on one of the first and second substrates. The optically functional transformation boundary surface allows the laser radiation to pass at least partially, such that a profile of the laser radiation is transformed into a top-hat profile.

Abstract: A device for deflecting laser radiation (8) with a waveguide (1) having an entrance face (6) and an exit face (7) spaced apart from each other in the Z-direction by a spacing (L), wherein the waveguide (1) has a greater extent in the X-direction than in the Y-direction, and at least two electrodes (4, 5) arranged on the waveguide (1), wherein a deflection voltage (+V, ?V) is applied to the at least two electrodes (4, 5), so that the laser radiation is electro-optically deflected in the waveguide (1) with respect to the X-direction, wherein the spacing (L) between entrance face (6) and exit face (7) has a dimension so that the profile of the laser radiation after exiting the exit face (7) corresponds to the profile of the laser radiation prior to entering the entrance face (6). The spacing (L) may correspond to the Talbot length of the laser radiation.
