TL;DR: In this paper, a three-cycle multi-millijoule pulse amplifier with 318 W power was reported. But this was achieved by compressing pulses of a Yb-fiber chirped pulse amplifier in a 6 m long stretched flexible hollow fiber.
Journal ArticleDOI
Multipass cell for high-power few-cycle compression.
TL;DR: In this paper, a multipass cell for nonlinear compression to few-cycle pulse duration is introduced composing dielectrically enhanced silver mirrors on silicon substrates, achieving high output beam quality (M2 < 1.2) and high spatio-spectral homogeneity (97.5%), as well as the compressibility of the output pulses to 6.9 fs duration.
Journal ArticleDOI
Ultra-short-pulse high-average-power Megahertz-repetition-rate coherent extreme-ultraviolet light source

TL;DR: In this article, the up-to-date most powerful table-top XUV source with 12.9 mW in a single harmonic line at 26.5 eV is demonstrated via HHG of a frequency-doubled and postcompressed fiber laser.
Journal ArticleDOI
Kilowatt-average-power compression of millijoule pulses in a gas-filled multi-pass cell.
TL;DR: It is demonstrated the reliable generation of 1-mJ, 31-fs pulses with an average power of 1 kW by post-compression of 200-FS pulses from a coherently combined Yb:fiber laser system in an argon-filled Herriott-type multi-pass cell with an overall compression efficiency of 96%.
Journal ArticleDOI
Temporal contrast enhancement of energeticlaser pulses by filtered self-phase-modulation broadened spectra.
TL;DR: In this article, a novel approach for temporal contrast enhancement of energetic laserpulses by filtered SPM broadened spectra was presented, which is applicable to a wide range of laser parameters and poses a highly efficient alternative to existing contrastenhancement methods.
