Abstract
The superluminal group velocity of an ultrashort optical Bessel beam pulse is measured over its entire depth of field, corresponding to approximately 2x10(4) optical wavelengths. The method used is to measure the traveling ionization front induced by the pulse.Year: 2002 PMID: 11863896 DOI: 10.1103/PhysRevLett.88.073901
