Abstract
The advantages of radially and azimuthally polarized laser beams for various applications in material processing, e.g. cutting and drilling, over circularly or linearly polarized beams has been reported among others in [1]. Furthermore, for micro material processing ultrafast lasers with pulse durations in the order of 1 ps have gained tremendous interest. The oscillator we present here is a promising candidate to seed a thin-disk multipass amplifier without the need of a complex multi-stages pre-amplification scheme as reported in [2].
