| Abstract: | The dynamics of the envelope of a new type of light field, a femtosecond Bessel light pulse (FBLP) formed from a Gaussian pulsed beam by means of a multi-circular diaphragm, has been investigated theoretically. It is shown that the FBLP possesses a steady structure that features a narrow central maximum and significantly suppressed subordinate maxima. |
