Efficient Spectral Broadening in the 100-W Average Power Regime Using Gas Filled Kagome HC-PCF and Pulse Compression

Florian Emaury, Clara J. Saraceno, Benoit Debord +6

We present nonlinear pulse compression of a high-power SESAM-modelocked thin-disk laser (TDL) using an Ar-filled hypocycloid-core Kagome Hollow-Core Photonic Crystal Fiber (HC-PCF)…

Breakdown of the Dipole Approximation in Strong-Field Ionization

A. Ludwig, J. Maurer, B. W. Mayer +3

We report the breakdown of the electric dipole approximation in the long-wavelength limit in strong-field ionization with linearly polarized few-cycle mid-infrared laser pulses at…

Mid-infrared pulse generation via achromatic quasi-phase-matched OPCPA

Benedikt W. Mayer, Christopher R. Phillips, Lukas Gallmann +1

We demonstrate a new regime for mid-infrared optical parametric chirped pulse amplification (OPCPA) based on achromatic quasi-phase-matching. Our mid-infrared OPCPA system is based…
