摘要

We develop a phenomenological model to investigate dynamics of ionization-induced injection.In the "bubble" regime of laser wakefield acceleration (LWFA),it is found that there is an upper limit for laser intensity of ionization-induced injection.In the plane perpendicular to the laser polarization,when the laser pulse is linearly polarized,ionization-induced injected electrons exhibit a filamented structure and semi-coherent betatron oscillation.
