2 Laser Sources for Ultrahigh Intensity Applications: Particle Acceleration and Radiation Generation High Peak power PW (10 23 W/cm 2 ) High Average power ~50kW High Efficiency >20% Output: 40J@1Hz = 40W 2

3 It s a light bulb. Output: 40J@1Hz = 40W Input:150kW Efficiency<

4 Why this obsession for Peak Power? Laser Peak power provides: o The Highest E fields to explore vacuum nonlinearity, dark matter, o Generation of high energy Particles from visible to TeV and possibly PeV o Shortest light bursts visible to Gamma Ray (as to zs) o Highest temperatures o Highest acceleration g IZEST a New Paradigm in Laser and High Energy Physics IZEST is based on large scale facilities developped over the past 20 years for Laser fusion Based on the large laser fusion, High Field Science, High energy fundamental Physics communities. Huge body of work in Plasma Physics 4

5 IZEST Triggering a Revolution in Laser Technology Driver Highest Peak Power will demand higher damage components based on Plasma Optics from J/cm2 to 10kJ/cm2 Laser Acceleration will enable 100GeV single stage to reach multistage TeV-PeV level Scientific and Societal Applications will require much higher and efficient average power: Project ICAN from single Watt to Megawatt IZEST Benefit from the largest Pump Lasers Up to the MJ PETAL-LMJ NIF LLNL 5

20 Thank you! IZEST is not ELI ELI is conceived to be an infrastructure aiming at many objectives. It is a user facility IZEST is the converse. It aim at one objective involving many infrastructures. It is a large R&D project. ELI aspires to be an european infrastructure While IZEST aims to be an international one. 20
