Towards direct nonlinear compression of energetic sub-nanosecond pulses to the ultrafast regime
Gaspard Beaufort, Nayla Jimenez, Gunnar Arisholm +5
Applications of terawatt-class lasers can enormously benefit from pulse trains with kHz repetition rates. The associated unprecedented combinations of peak and average powers requi…
Soft X-ray high-harmonic generation in an anti-resonant hollow core fiber driven by a 3 m ultrafast laser
Drew Morrill, Will Hettel, Daniel Carlson +15
High-harmonic upconversion driven by a mid-infrared femtosecond laser can generate coherent soft X-ray beams in a tabletop-scale setup. Here, we report on a compact ytterbium-pumpe…
Towards High-Energy Few-Cycle Optical Vortices with Minimized Topological Charge Dispersion
Federico J. Furch, Gunnar Arisholm
A simple approach to generate high-energy few-cycle optical vortices with minimized topological charge dispersion is introduced. By means of numerical simulations it is shown that,…
Spectral broadening in convex-concave multipass cells
Kilian Fritsch, Victor Hariton, Kevin Schwarz +3
Since its first demonstration in 2016, the multi-pass spectral broadening technique has covered impressive ranges of pulse energy (3 J - 100 mJ) and peak power (4 MW - 100 GW).…
Few-cycle pulse generation by double-stage hybrid multi-pass multi-plate nonlinear pulse compression
Anne-Lise Viotti, Chen Li, Gunnar Arisholm +4
Few-cycle pulses present an essential tool to track ultrafast dynamics in matter and drive strong field effects. To address photon-hungry applications, high average power lasers ar…
Multi-gigawatt peak power post-compression in a bulk multi-pass cell at high repetition rate
Ann-Kathrin Raab, Marcus Seidel, Chen Guo +5
The output of a 200 kHz, 34 W, 300 fs Yb amplifier is compressed to 31 fs with > 88 % efficiency to reach a peak power of 2.5 GW, which to date is a record for a single-stage bulk…
