Designed in collaboration between CNRS, CEA, Ecole Polytechnique, the Paris Saclay University and their industrial partners, the upcoming "Apollon" laser facility on the plateau of Saclay, South of Paris (France), is expected to reach for the first the 10 Petawatt power level. At the heart of the opportunities offered by the facility will be compact particle acceleration, in particular testing...

Laser-plasma interactions in relativistic regime brought a tremendous advancements of compact particle accelerators and radiation sources. Rapid progresses of ultashort high-power laser technology has reached to output power of PW, which can provide a chance to explore new regime of relativistic laser-plasma interactions. We have developed two PW Ti:Sapphire laser beamlines with the peak...

1 - Introduction and context
For the last decade, ytterbium-doped fiber amplifiers have been demonstrating their strong potential to amplify ultrashort pulses at high average powers, close to the kilowatt level [2]. Indeed, the low quantum defect of the ytterbium ion and the high surface-to-volume ratio of the fiber geometry provide a very good thermal handling, allowing the amplification of...

Plasma-based laser amplification has been recently receiving much attention. Using a plasma as an amplifying medium opens new possibilities in manipulating laser light at high intensities since it overcomes solid state based technology that is limited by the damage threshold of optical components. A plasma amplifier is based on the interaction and energy exchange between a long...

The maximum extractable energy of conventional chirped pulse amplification (CPA) laser technology is limited by the damage threshold of laser components, which is in the order of $10^{12} W/cm^2$. Amplification by Stimulated Raman Back Scattering (SRBS) in plasma has the potential to overcome these limitations allowing theoretically maximum intensities of $10^{16}$ – $10^{17} W/cm^2$, which is...

Efficient multistage compression of petawatt laser pulses, such as those becoming available at laser facilities around the world, holds the promise of exawatt, X-ray pulses. A shorter route to the generation of Schwinger intensities with current day technology is now envisioned with the capability of producing high energy radiation and particle beams of extremely short, sub-attosecond...

Existing high peak power, chirped pulse amplification (CPA) systems are limited by intensity dependent damage of final optics, i.e. intensity-depended damage of final compressor gratings and downstream focusing optics. For kJ-class pulse production these systems are further limited in the amount of energy that can be safely extracted from the laser amplifier by the limited duration of the...
