Abstract :
We describe a transparent dielectric accelerator structure that is designed for ultra-short laser pulse operation. The structure is based on the principle of periodic field reversal to achieve phase synchronicity for relativistic particles. To preserve the possibility of ultra-short pulse operation it does not resonate the laser field in the vacuum channel, which enables the structure to support higher peak electric fields. Gradients on the order of a few GeV/m are expected to be possible with 10 fsec laser pulses. The proposed structure has a two-dimensional geometry which is ideally suited for micro-fabrication techniques and for integration with other optical MEMs components.
