Abstract
The excitation of plasma waves over a length of up to 8 cm is demonstrated using laser guiding of intense laser pulses through hydrogen-filled glass capillary tubes. The plasma waves are diagnosed by spectral analysis of the transmitted laser radiation. The dependence of the spectral redshift—measured as a function of filling pressure, capillary tube length, and incident laser energy—is in excellent agreement with simulation results. The longitudinal accelerating field inferred from the simulations is in the range of 1–10 GV/m.
