We demonstrate the impact of the optics roughness in Öffner stretchers used in chirped pulse amplification laser chains and how it is possible to improve the temporal contrast ratio in the temporal range of 10–100 ps by adequately choosing the opt

In the aim of reaching high-peak-powers, which may induce deleterious thermal loads, we investigate the spatiotemporal thermal distortions in a PW-laser facility studying the thermal effects (up to 130W/cm²) occurring in a large compressor-gratings.

Surfaces with superimposed patterns offer, in many applications, numerous advantages over traditional smooth surfaces since they profoundly affect functional behavior, e.g., friction, wettability, etc. Different shapes and sizes of surface patterns w

The objective of the Apollon 10 PW project is the generation of 10 PW peak power pulses of 15 fs at $1~\text{shot}~\text{min}^{-1}$ . In this paper a brief update on the current status of the Apollon project is presented, followed by a more detailed

We present a high-contrast 10-fs Front-End for Ti:sapphire PW-lasers within the Apollon-10PW project. This injector uses OPCPA pumped at 100Hz by Yb-based CPA chain. Combination of OPCPA and XPW permits a >1012 contrast ratio.

The wavefront aberrations in a large-scale, flash-lamp-pumped, high-energy, high-power glass laser system can degrade considerably the quality of the final focal spot, and limit severely the repetition rate. The various aberrations induced on the Lab
