Passion Extreme Light

Extreme-light laser is a universal source providing a vast range of high energy radiations and
particles along with the highest field, highest pressure, temperature and acceleration. It offers the
possibility to shed light on some of the remaining unanswered questions in fundamental physics like
the genesis of cosmic rays with energies in excess of 10 ²⁰ eV or the loss of information in black-holes.
Using wake-field acceleration some of these fundamental questions could be studied in the laboratory.
In addition, extreme-light makes possible the study of the structure of vacuum and particle production
in "empty" space which is one of the field’s ultimate goal, reaching into the fundamental QED and
possibly QCD regimes.
Looking beyond today’s intensity horizon, we will introduce a new concept that could make
possible the generation of attosecond-zeptosecond high energy coherent pulse, de facto in x-ray
domain, opening at the Schwinger level, the zettawatt, and PeV regime; the next chapter of laser-
matter interaction.
