Development of Diffraction-Free Space-Time Optical Beams
Abstract
UCF propose to theoretically investigate and experimentally synthesize and characterize a new class of pulsed optical beams that we call ~space-time~ beams. Unlike traditional optical beams where the spatial and temporal degrees of freedom are usually uncoupled, space-time beams feature tightly correlated spatiotemporal characteristics. A surprising consequence of these correlations is that such beams are almost diffraction-free and propagate for extended distances with minimal change in their transverse profile or pulse shape. Such beams will be useful in probing through scattering media, standoff detection, optical imaging and microscopy, and potentially in filamentation studies and potentially for laser weaponry.
