Direct Laser Acceleration

Dielectric Laser Acceleration​ Group

In the Dielectric Laser Acceleration (DLA) Group, operating under SLAC Project E-163, we investigate the physics of laser linear acceleration in dielectric media. We experimentally test electron bunching at optical wavelengths, a key step in developing particle sources for laser accelerators, and devise and test optical-scale structures suitable for staged laser acceleration. This experimental effort is part of the Accelerator on a Chip International Program (ACHIP)​, led by Stanford University and Friedrich Alexander University Erlangen.
