We present a thin-disk multipass amplifier as a power-scaling architecture for ultrafast ps and fs lasers. The system is industrially stable and supports burst functionality. Only minimal CPA is needed.

Stress-induced birefringence leads to losses in solid-state laser resonators and amplifiers with polarized output beams. A model of stress-induced birefringence in thin disks is presented, as well as measurements of stress-induced birefringence in a

We present a linear multipass amplifier based on the thin-disk technology which allows power scaling of continuous-wave, pulsed, and ultrashort-pulsed lasers without change of beam characteristics. The flexibility of the seed laser, such as choice of

An ultrafast Yb-doped thin-disk multi-pass laser amplifier system with flexible parameters for material processing is reported. We can generate bursts consisting of four pulses at a distance of 20 ns and a total energy of 46.7 mJ at a repetition rate

Defects and process irregularities influence the bonding strength and thus the stability and lifetime of welded glass components. The present paper proposes to monitor the laser-based glass welding process by means of a single photodetector that reco

A Yb:YAG thin-disk multi-pass laser amplifier pumped at 941 nm delivers 2.3 mJ of pulse energy at 1.4 kW average output power, 950 fs pulse duration and M2 < 1.8 beam quality. Zero-phonon-line pumping at 969 nm improves M2 to below 1.4 at 1.8 mJ puls
