摘要：
A family of dispersionless and diffractionless spatial-temporal Gauss-Laguerre waves propagating in dispersive linear and transparent media is introduced. Contrary to pulsed Bessel beams and envelope-X waves recently studied in media with normal dispersion, these spatiotemporal Gauss-Laguerre beams may exist both in the normal and anomalous dispersion spectral regions of the medium.
