Abstract The development of optical metrology suited to ultrafast lasers has played a key role in the progress these light sources last few decades. Measurement techniques providing complete E -field ultrashort laser beams both time and space are now being developed. Yet, they had so far not been applied most powerful lasers, which reach PetaWatt range by pushing chirped pulse amplification (CPA) scheme its present technical limits. This situation left doubts on their actual performance,...
The combination of temporal chirp with a simple chromatic aberration known as longitudinal chromatism leads to extensive control over the velocity laser intensity in focal region an ultrashort beam. We present first implementation this effect on femtosecond laser. demonstrate that by using specially designed and characterized lens doublet induce chromatism, can be implemented independent parameters focusing optic, thus allowing for great flexibility experimental applications. Finally, we...
The investigation of spatio-temporal couplings (STCs) broadband light beams is becoming a key topic for the optimization as well applications ultrashort laser systems. This calls accurate measurements STCs. Yet, it only recently that such complete or spatio-spectral characterization has become possible, and so far mostly been implemented at output systems, where experiments take place. In this survey, we present first time STC different stages collection high-power all based on chirped-pulse...
Abstract Following the successful Run 1 experiment, Advanced Proton Driven Plasma Wakefield Acceleration Experiment (AWAKE) Run2 experiment requires design and implementation of a compact electron source. The “high-quality Electron Accelerator driven by Reliable Laser wakefield for Industrial uses” (EARLI) project aims to stand-alone high-quality injector based on laser accelerator (LWFA) as an alternative proposal AWAKE’s baseline X-band gun. This is currently in phase, including...
Particle flux is not enough for societal applications when using TW/PW class lasers to generate high energy electron. To overcome this, we have developed a 100 Hz Joule TiSa laser and report initial results.
Joule class lasers at 100Hz with ultra-short pulse involve a lot of challenges to manage thermal issues in the amplifiers as well compressors. Recent results achieved this direction are presented.
One of the major achievements optics in recent decades has been generation light pulses extremely short duration, down to a few femtoseconds 1990's and tens attoseconds past years. Throughout development these sources, ability accurately measure temporal properties ultrashort crucial. Several well-established techniques are now available their electric field E(t) from femtosecond attosecond range. However, within any beam, pulse can vary spatially vice versa. Such correlations between...

This talk will present the intriguing new possibilities offered by spatio-temporal shaping of ultrashort laser beams, and some latest developments on metrology femtosecond lasers, up to PetaWatt power level.
We report the demonstration of 100Hz, 300mJ TiSa amplifier. The amplifier is based on active-mirror concept, with efficient cooling capacity, and pumped by frequency-doubled Nd:YAG laser emitting 700mJ at 532nm.
Modern laser plasma accelerators require combination of high peak power and average from the laser. Ti:Sa CPA remaining best technology for such purpose a amplifier has been developed
