Influence of the laser pulse duration in high-order harmonic generation

Saga Westerberg, Melvin Redon, Ann-Kathrin Raab +10

High-order harmonic generation (HHG) in gases has been studied for almost 40 years in many different conditions, varying the laser wavelength, intensity, focusing geometry, target…

Time-resolved photoemission electron microscopy on a ZnO surface using an extreme ultraviolet attosecond pulse pair

Jan Vogelsang, Lukas Wittenbecher, Sara Mikaelsson +6

Electrons photoemitted by extreme ultraviolet attosecond pulses derive spatially from the first few atomic surface layers and energetically from the valence band and highest atomic…

Measurement of Ultrashort Laser Pulses With a Time-Dependent Polarization State Using the D-Scan Technique

Daniel Diaz Rivas, Ann-Kathrin Raab, Chen Guo +4

The dispersion scan (d-scan) technique is extended to measurement of the timedependent polarization state of ultrashort laser pulses. In the simplest implementation for linearly po…

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…

Characterizing ultrashort laser pulses with second harmonic dispersion scans

Ivan Sytcevich, Chen Guo, Sara Mikaelsson +9

The dispersion scan (d-scan) technique has emerged as a simple-to-implement characterization method for ultrashort laser pulses. D-scan traces are intuitive to interpret and retrie…

Post-compression of picosecond pulses into the few-cycle regime

Prannay Balla, Ammar Bin Wahid, Ivan Sytcevich +18

In this work, we demonstrate post-compression of 1.2 picosecond laser pulses to 13 fs via gas-based multi-pass spectral broadening. Our results yield a single-stage compression fac…

Few-cycle lightwave-driven currents in a semiconductor at high repetition rate

Fabian Langer, Yen-Po Liu, Zhe Ren +9

When an intense, few-cycle light pulse impinges on a dielectric or semiconductor material, the electric field will interact nonlinearly with the solid, driving a coherent current.…
