COLLIMATION AND FOCUSING OF PARAXIAL WAVE PACKET OBTAINED BY DIFFRACTION IN THE FAR AREA OF INITIAL SINGLE-CYCLE WAVE
It is shown that during the collimation of paraxial wave packet generated by diffraction in the far area of initial single-cycle wave a "W-shaped" 1.5 cycle spatiotemporal structure is formed, and its duration is proportional to the distance from the beam axis, and its central part is movi...
