Directly measuring the spatiotemporal electric field of ultrashort Bessel-X pulses
arXiv:0904.1817 · doi:10.1364/OL.34.002276
Abstract
Using SEA TADPOLE with micrometer-range spatial and femtosecond-range temporal resolution, we report the first direct spatiotemporal measurements of ultrashort Bessel-X pulses. We demonstrate their propagation invariance and superluminal velocity and verify our results with simulations
