Recently, the race to build a petawatt or even higher-power laser system with the pulse duration of few tens of femtosecond is initiated worldwide. Such ultrahigh-peak-power laser systems are greatly benefit for fundamental research areas, such as accelerating the charged particles (electrons and protons), and generating high-energy photon (X-ray and γ-ray) sources. The Shanghai Super-intense...

The recent experiments with high power Ti: Sapphire laser pulses demonstrate that it is not possible to produce a homogeneous beam pattern. Hot zones are situated across the beam cross section. Each hot zone self-focuses into a filament, if the intensity and power are high enough. Each of the multiple filaments has a core intensity clamped down to that of a single filament of the order of...

Like in astronomy, Adaptive Optics (AO) has recently become a standard feature at the modern ultra-high intensity lasers facilities. AO aims in reaching both maximum peak energy and intensity by correcting both the thermal effects induced in the amplification stages and aberrations induced by the optical components of the laser chain. The new generation of ultra-high intensity femto-second...

Laser wakefield theory shows that for a given laser, the energy gain and accelerating length are both inversely proportional to the plasma density [1]. This means that the lower the gas density, the longer the acceleration distance, which is undesirable in reaching ultra-high energies. The recent proposed generation of the X-ray laser pulse provides an attractive way to achieve ultrahigh...

In the recent years, 10 Peta-watt (PW) laser system is a hot topic in the field of laser technology. Many countries and laboratories are building or having a plan to build a 10 PW laser system [1, 2]. The CPA technique particularly using Ti:sapphire (Ti:S) CPA systems is still the main method to achieve PW and 10 PW-levels laser pulses for its high efficiency and stability [3, 4]. However, the...

High-peak-power laser beams with a top-hat transverse intensity profile are shown to offer unique options for the spectral and temporal nonlinear-optical transformations of high-intensity laser fields, promising a new technology of spatially uniform pulse compression at the subpetawatt level of peak powers.

Imagine Optic works since early 2000 on Hartmann sensors and has acquired a unique expertise in X-ray wavefront sensing showing outstanding results. The very first experiment performed on the Advanced Light Source beamline at Lawrence Berkeley National Laboratory, USA in 2003 reached accuracy better than λEUV/120 rms (0.11 nm) at the wavelength of 13.4 nm [1]. Later we also demonstrated...

Over the past years, the ultra-intense laser field has continued to flourish as demonstrated by a growing number of scientific and technological projects. In particular, Europe’s commitment towards ultra-high intensity physics is exemplified by the involvement of several European countries pooling research, network resources and experience to succeed in the completion of different state of the...

Dr Christophe Radier (Thales)Poster Session
High peak power lasers for Ultra High Intensity (UHI) physics have been developed for almost two decades. The first generation of such lasers has been essentially built with Nd:Glass Chirped Pulse Amplifiers (CPA) operating at very low repetition rates (few shots per day).
The last decade has seen the tremendous development of CPA based on Titanium Sapphire crystals pumped by the second...
