摘要

Localized optical Airy Bessel configuration wave packets were first generated on the basis of a grating-telescope combination (Nat.Photon.4 (2010)103).By studying the spatially induced group velocity dispersion effect of ultrashort pulsed Bessel beams during propagation,we find the universal physical foundation of generating Airy-Bessel wave packets (ABWs) in free space.The research results are expected to open up more common channels for generating stable linear localized ABWs.
