Super-intense lasers is a research field focused on the generation, manipulation, and application of light pulses exhibiting peak intensities exceeding 10¹⁸ W/cm². This field investigates phenomena occurring under extreme electromagnetic fields, such as relativistic laser-plasma interactions, high-energy particle acceleration, and the study of matter under conditions relevant to astrophysics or inertial confinement fusion. Characterized by ultra-high peak power (terawatts to petawatts) and ultra-short pulse durations (femtoseconds), this research holds significance for advancing fundamental physics, developing compact particle accelerators and advanced radiation sources, and exploring pathways towards controlled nuclear fusion.
