From: Dephasingless laser wakefield acceleration in the bubble regime

Laser pulse and bubble evolution in a dephasingless laser wakefield accelerator. Snapshots of the laser intensity (bottom) and plasma density (top) at various distances for the schematic in Fig. 2b. In (a–c), the plasma begins 0.54 cm into the focal region. In (d–g), the plasma begins 0.465 cm into the focal region. (c,g) Correspond to the same spatial ___location, but the deformation of the bubble due to trapped light is only observed in (c).
