Debris mitigation techniques for petawatt-class lasers in high debris environments
Physical Review Special Topics. Accelerators and Beams, 2010 This paper addresses debris mitigation techniques for two different kinds of debris sources that are found in the high-energy density community. The first debris source stems from the laser-target interaction and this debris can be mitigated by avoiding ...
