| Abstract: | A formula is developed to describe the propagation of beams driven by few-cycle Gaussian pulse in a media with group velocity dispersion (GVD). With the method, the spatiotemporal evolution of the pulsed beam can be straightforwardly quantified as long as the monochromatic beam solutions in free space, which have been widely investigated in previous works, are known. The method makes it possible to analytically deal with the few-cycle pulsed beams with transverse profiles other than the Gaussian one, which is, to our knowledge, the one mainly investigated previously, in GVD media. |
