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<br />Comment: 2 pages 1 figure Submitted to CLEO/IQEC 09 on December 2, 2008
