Abstract
The plasma electron density oscillation produced in the wake of a narr ow (beam waist much less than plasma wavelength) ultrashort laser puls e is measured for the first time, with a temporal resolution much bett er than the electron plasma period and a high spatial resolution along the laser focal spot diameter. The relative density perturbation is b etween 30% and 100%, in good agreement with numerical simulations.
