Interactions of Laser Light at its Highest Intensity

Discussed are the relativistic interactions of ultra-high-intensity light with matter, which are studied with the 150-terawatt-peak-power Diocles laser, which was recently commissioned at the University of Nebraska, Lincoln.  Bright, ultrashort-duration (femtosecond) pulses of energetic x-rays and charged-particle beams are generated.  The applications of these unique radiation sources to problems in physical science, biomedicine, defense and homeland security will also be covered.
