We experimentally analyze a Bessel beam produced with a conical mirroR. paying particular attention to its superluminal and diffraction-free properties. We spatially characterized the beam in the radial and on-axis dimensions, and verified that the transverse profile is constant over a distance of 73 cm.

Abstract
We experimentally analyze a Bessel beam produced with a conical mirroR. paying particular attention to its superluminal and diffraction-free properties. We spatially characterized the beam in the radial and on-axis dimensions, and verified that the transverse profile is constant over a distance of 73 cm. In addition, we measured the superluminal phase and group velocities of the beam in free space. Both spatial and temporal measurements show good agreement with the theoretical predictions. © 2009 American Institute of Physics.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione
