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.
介绍了一类在色散线性透明介质中传播的无弥散和无衍射时空高斯 - 拉盖尔波。与最近在具有正常色散的介质中研究的脉冲贝塞尔光束和包络 - X波不同，这些时空高斯 - 拉盖尔光束可能存在于介质的正常色散和反常色散光谱区域中。
