Description
We will present recent observations in which a pulse front tilted laser is used to accelerate electrons along a 0.5mm dual-grating dielectric laser accelerator (DLA). The tilted pulse front provides group velocity matching of the laser to the electron beam, allowing us to take advantage of the high accelerating gradient provided by an ultrafast laser; while free space optics are used to manipulate the laser wavefront in order to maintain phase synchronicity over many hundreds of optical cycles. The extended electron-laser interaction lasts for a substantial fraction of a synchrotron oscillation, introducing the possibility to study electron dynamics in a DLA.
