Compressing High Energy Lasers through Optical Polymer Films Open
The thin-film post-compression technique has the ability to reduce the pulse duration in PW-class lasers, increasing the peak power. Here, the nonlinear response of an increasingly available optical thermoplastic demonstrates enhanced spec…

Towards subpicosecond pulses from solid target plasma based seeded soft X-ray laser Open
We investigate the coherence of plasma-based soft X-ray laser (XRL) for different conditions that can alter the electron density in the gain region. We first measure the source temporal coherence in amplified spontaneous emission (ASE) mod…
Highly multimodal structure of high topological charge extreme ultraviolet vortex beams Open
Optical beams carrying orbital angular momentum are a very active field of research for their prospective applications, especially at short wavelengths. We consider here such beams produced through high-harmonic generation (HHG) in a rare …
Laser-Plasma Acceleration Modeling Approach in the Case of ESCULAP Project. Open
Objective of ESCULAP project is the experimental study of Laser-Plasma Acceleration (LPA) of relativistic electron bunch from photo-injector in 10 cm length plasma cell *. In parallel, numerical tools have been developed in order to optimi…
Modeling of laser-plasma acceleration of relativistic electrons in the frame of ESCULAP project Open
We present numerical simulations results on the injection and acceleration of\na 10 MeV, 10 pC electrons beam in a plasma wave generated in a gas cell by a\n2J, 45 fs laser beam. This modeling is related to the ESCULAP project in which\nth…
A Start to End Simulation of the Laser Plasma Wakefield Acceleration Experiment at ESCULAP Open
We present a start to end (s2e) simulation of the Laserplasma Wake Field Accelerator (LPWA) foreseen as the ESCULAP project. We use a photo injector to produce a 5 MeV 10 pC electron bunch with a duration of 1 ps RMS, it is boosted to 10 M…
Synchronization of a Photo-Injector and a High Power Laser With Independent Clocks Open
The plasma acceleration project ESCULAP (ElectronS CoUrts pour L'Acc\'el\'eration Plasma) aims at studying electrons injection into a laser plasma accelerator. This requires the injection of short electron bunches generated by the photo in…
One long and two short pumping pulses control for plasma x-ray amplifier optimization Open
Development of efficient soft x-ray laser plasma amplifiers adapted to seeded operation, requires a better control over amplifier transverse spatial extent, brilliance control and gain lifetime. Here it is shown that pumping the plasma amp…
