Gouy phase是什么

Webresult of the Gouy phase shift.6,8,9 Even for few-cycle laser pulses, the phase anomaly was observed with respect to their carrier envelope owing to stabilization of the carrier-envelope phase.10 In addition, there is a myriad of evidence that the Gouy phase shift is a universal phenomenon for all focused WebAbstract. We show explicitly that the well-known Gouy phase shift of any focused beam originates from transverse spatial confinement, which, through the uncertainty principle, …
