Abstract

The influence of wavebreaking on Raman amplification is investigated. A phenomenological modification is added to a set of slowly varying envelope equations, and found to give good agreement to particle-in-cell simulations for cold plasma in the wavebreaking regime.

For warm plasma, good agreement is not found using the warm wavebreaking limit. However, the PIC simulations show that the decreased wavebreaking limit does have a significant impact on amplification. The limitations of our model are discussed, and possible future work outlined.
