How to Create Waves With a Laser Beam

The idea is to create stronger electric fields in a plasma without anything breaking down. You can use a high intensity laser to dump a lot of energy into the plasma which creates these fields and then accelerates particles to very high energy. So then you dump in a particle bunch that you're trying to accelerate and they move through the plasma following this wake, following the wake of these electrons. They're sort of like the surfers.
