Enhanced dynamic range spatio-spectral metrology of few-cycle laser pulses

Cristian Alexe, Aaron Liberman, Saga Westerberg +13

Accurate spatio-temporal and spatio-spectral metrology is critical to the characterization and use of ultra-short, high-power lasers. The emergence of few cycle pulses, with bandwi…

Compact, intense attosecond sources driven by hollow Gaussian beams

Rodrigo Martín-Hernández, Melvin Redon, Ann-Kathrin Raab +9

High-order harmonic generation (HHG) enables the up-conversion of intense infrared or visible femtosecond laser pulses into extreme-ultraviolet attosecond pulses. However, the high…

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…

Highly versatile, two-color setup for high-order harmonic generation using spatial light modulators

Ann-Kathrin Raab, Marvin Schmoll, Emma R. Simpson +7

We present a novel, interferometric, two-color, high-order harmonic generation setup, based on a turn-key Ytterbium-doped femtosecond laser source and its second harmonic. Each int…

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…
