We report on a passively mode-locked oscillator based on an erbium-doped dual concentric core fiber combining high normal dispersion and large mode area. This large normal dispersion laser generates long pulses with 30 ps duration and 0.17 nm spectra

We will present the advantages of the single-crystal-fiber (SCF) concept and review the main results obtained in ultrashort multi-stages Yb:YAG SCF amplifiers for high average power (100W) and high energy (mJ) regimes using Divided-Pulse-Amplificatio

International audience; Power scaling of end-pumped laser rod amplifiers is challenging due to beam distortions at high powers. It is difficult to understand these distortions since several physical effects contribute at the same time. We present a d

The amplification of a high-power radially polarized beam in a thin-disk multipass amplifier is presented. Up to 265W output power at a pulse duration of 782 fs and a high degree of radial polarization is achieved.
