A laser system producing controllable and stable pulses with high power and ultrashort
duration at high repetition rate is a key component of a high energy laser-plasma accelerator …

We present an experimental demonstration of a renewed set up, with respect to the one
described in [A. Jullien et al, Opt. Lett. 30, 920 (2005)], that enables more reliable and robust …

Experimental measurements of proton acceleration with high intensity and high-contrast
short laser pulses have been carried out over an order of magnitude range in target …

Cross-polarized wave (XPW) generation is used for the contrast improvement of ultra-
intense femtosecond laser pulses in a double CPA configuration. We present theoretical and …

We propose a highly efficient scheme for temporal filters devoted to femtosecond pulse
contrast enhancement. The filter is based on cross-polarized wave generation with a …

We report on a compact energy-scalable device for generating high-fidelity femtosecond
laser pulses based on spatial filtering through a hollow-core fiber followed by a nonlinear …

We report here an alternative and more efficient orientation of cubic crystals for generation of
cross-polarized femtosecond laser pulses. We show both theoretically and experimentally …

The efficiency of χ^(3)-based cross-polarized wave generation in cubic crystals is
investigated for different crystal orientations. It is shown that holographic-cut orientation is …

The characterization of a temporal filter based on cross-polarized wave generation working
in the few-optical-cycle regime is presented. We show that this device dramatically improves …

Based on cross-polarized wave generation, a robust front-end is designed for improving
pulse temporal quality of a petawatt Ti: sapphire laser. High-contrast seed pulses with 105 …
