Extreme light is one of the most exciting domains in the laser field today. It relies on the generation of ultra high peak power obtained by delivering the energy over a short time. Today, laser peak power exceeds typically the PW or thousand times the world grid power. The ability to produce and focus this gargantuan power over a size 10 times smaller than a hair offers unfathomable...

The question of whether Hawking evaporation violates unitarity, and therefore results in the loss of information, remains unresolved since Hawking's seminal discovery. So far the investigations remain mostly theoretical since it is almost impossible to settle this paradox through direct astrophysical black hole observations. Here we point out that relativistic plasma mirrors induced by...

Radiation Pressure Acceleration is quite promising for ion acceleration. In order to improve the laser energy transmission efficiency and restrain instabilities such as RTI and hole boring, an ultra-high intensity, ultra high contrast laser pulse with steep front is required and therefore a plasma lens with near critical density is proposed. When the laser passes through the nearly critical...

We discuss proton acceleration with 10PW lasers. In 2001, we proposed proton acceleration with light pressure for the first time [1]. Then in 2007, we explained that light pressure acceleration is actually multistaged acceleration of collisionless electrostatic shock driven by the laser pressure [2, 3]. However, the method of light pressure is hard to support proton acceleration of energy...

Interaction of high-intensity laser pulses with solid targets results in generation of large quantities of energetic electrons that are the origin of various effects such as intense x-ray emission, ion acceleration, and so on. Some of these electrons are escaping the target, leaving behind a significant positive electric charge. The electrons that are accelerated in the backward and forward...

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.

A relativistic flying mirror is breaking wake wave excited in tenuous plasma by an intense, short laser pulse. This highly nonlinear wave has a singularity of electron density and has a velocity nearly equals to the speed of light. Thus the electrons can work as a partially reflecting mirror moving nearly at the speed of light. This concept was first proposed by Bulanov et al. So far some of...
