Abstract Text:
'Laser-plasma acceleration' has been synonymous with laser-driven plasma waves providing the (electrostatic) accelerating fields. This process has a very steep intensity threshold. Direct acceleration of charged particles by electromagnetic fields, however, has been limited by diffraction, phase matching, and material damage thresholds. A recently developed plasma micro-optic [B. Layer et al., Phys. Rev. Lett. 99, 035001 (2007)] removes these limitations and promises to allow high-field acceleration of electrons over many centimeters using relatively small millijoule-scale femtosecond lasers. We present preliminary experiments and simulations for these plasma 'slow wave' structures.
