WebGouy phase shift is a universal phenomenon for all focused waves including nondiffracting beams (e.g., Airy and Bessel beams),12−15 radially polarized beams,16,17 and vortex beams.18,19 Also, the Gouy phase shift is accumulated while a beam propagates plural optical components.20 WebMar 17, 2004 · Retrieved CE Gouy phase shift as a function of the propagation distance in the focus. The solid line is the Gouy phase of a cw Gaussian beam, shown for comparison. Note that, in the outer part of the focus, the electron count rate rapidly decreases, making detection of additional experimental points difficult. Reuse & Permissions
