Abstract

We report on multi-100W ultrafast laser sources based on industrialized components which deliver pulse energies starting from sub-mJ to well exceeding 200mJ. These sources are based on ytterbium-doped laser media which intrinsically have very high efficiencies and therefore allow for stable operation at high average powers but are limited due to the supported bandwidth to some 100fs pulse durations. The presented setups compress this type of pulses to well below 50fs with a single SPM-based stage which adds approximately an order of magnitude in pulsed peak power. Adding a second stage allows for even shorter pulses in the few-cycle regime where even the carrier-envelope phase of the pulses is of relevance and consequently has to be characterized and stabilized.
