8. QCD ~1035W/cm2 EQ=mpc2 Relativistic Compression Ultra Relativistic
NL Optics
Ultra-relativistic intensity is
defined with respect to the proton
EQ=mpc2, intensity~1024W/cm2

9. ELI Cardinal Features Ultra High intensity
Relativistic and ultrarelativistic regime
Ultrashort Pulse of high energy radiations and particles because
(Power-Pulse Duration Conjecture)
Pristine synchronization between beams within a fraction of the period

10. Unique laser properties:
- ultrahigh fields
- ultrashort pulses
Novel techniques:
- production of brilliant photon beams

11. Peak Power -Pulse Duration Conjecture
To get high peak power you must decrease the pulse duration.
To get short pulses you must increase the intensity

12. Relativistic and Ultra R

23. Expectations
Romania must do its share. It must become the world premier facility in Laser-Based Nuclear Physics.
Must become a recognized pan-european Infrastructure, with collaboration from the ELI Partners (Cz, Hu, De, Fr, UK, …..) and beyond.
