Resonant phase matching by oblique illumination of a dielectric laser accelerator
Resonant phase matching by oblique illumination of a dielectric laser accelerator
In dielectric laser-driven accelerators (DLA), careful tuning of drive-laser wavelength and structure periodicity is typically required in order to hit the resonant condition and match the phase velocity of the accelerating wave to the electron beam velocity. By aggressively detuning (up to 30 mrad) the angle of incidence of the …
