A 57 W radially polarized SESAM mode-locked thin-disk oscillator
2017
The advantages of radially and azimuthally polarized laser beams for various applications in materi processing, e.g. cutting and drilling, over circularly or linearly polarized beams has been reported amoi others in [1]. Furthermore, for micro material processing ultrafast lasers with pulse durations in the ord of 1 ps have gained tremendous interest. The oscillator we present here is a promising candidate to seed thin-disk multipass amplifier without the need of a complex multi-stages pre-amplification scheme reported in [2].
