Observation of laser power amplification in a self-injecting laser wakefield accelerator
We report on the depletion and power amplification of the driving laser pulse in a strongly driven laser wakefield accelerator. Simultaneous measurement of the transmitted pulse energy and temporal shape indicate an increase in peak power from 187 ± 11 TW to a maximum of 318 ± 12 TW after 13 mm of p...

| description | We report on the depletion and power amplification of the driving laser pulse in a strongly driven laser wakefield accelerator. Simultaneous measurement of the transmitted pulse energy and temporal shape indicate an increase in peak power from 187 ± 11 TW to a maximum of 318 ± 12 TW after 13 mm of propagation in a plasma density of 0.9 × 1018 cm−3. The power amplification is correlated with the injection and acceleration of electrons in the nonlinear wakefield. This process is modeled by including a localized redshift and subsequent group delay dispersion at the laser pulse front. |
