We apply quasi-phasematching, enabled by axially modulated plasma channels, to overcome this limitation. By matching the modulation period to the dephasing length, a relativistic electron can undergo energy gain over several dephasing lengths. Theory and simulations are presented showing that at a weakly relativistic laser intensity, ~10^17 W/cm2, and millijoule level pulse energies, quasi-phasematched LWFA results in energy gains of 50 MeV larger than standar ... 16:00 - 18:00 Biweekly Seminar Predication: Neutral, Committal, or Modally Committal School PHILOSOPHY Predication: Neutral, Committal, or Modally Committal https://www.skyroom.online/ch/ipmseminars/ipm-seminars-fall2021 User: biweeklyseminars Pass: biweeklyseminars ... |
