Abstract
We describe theoretically and verify experimentally a novel class of diffraction-free pulsed optical beams that are `Omni-resonant': they have the remarkable property of transmission through planar Fabry-Perot resonators without spectral filtering even if their bandwidth far exceeds the cavity resonant linewidth. Ultrashort wave packets endowed with a specific Spatio-temporal structure couple to a \textit{single} resonant mode independently of its linewidth. We confirm that such `space-time' Omni-resonant wave packets retain their bandwidth (1.6~nm), Spatio-temporal profile (1.3-ps pulse width, 4-m beam width), and diffraction-free behavior upon transmission through cavities with resonant linewidths of 0.3-nm and 0.15-nm.
