Pang, X. (author), Fischer, D.G. (author), Visser, T.D. (author)We study the Gouy phase of a scalar wavefield that is focused by a lens suffering from primary spherical aberration. It is found that the Gouy phase has different behaviors at the two sides of the intensity maximum. This results in a systematic increase of the successive wavefront spacings around the diffraction focus. Since all lenses have some...journal article 2013

Pang, X. (author), Visser, T.D. (author)The Gouy phase, sometimes called the focal phase anomaly, is the curious effect that in the vicinity of its focus a diffracted field, compared to a non-diffracted, converging spherical wave of the same frequency, undergoes a rapid phase change by an amount of ?. We theoretically investigate the phase behavior and the polarization ellipse of a...journal article 2013

Pang, X. (author), Fischer, D.G. (author), Visser, T.D. (author)The Gouy phase, sometimes called the phase anomaly, is the remarkable effect that in the region of focus a converging wave field undergoes a rapid phase change by an amount of ?, compared to the phase of a plane wave of the same frequency. This phenomenon plays a crucial role in any application where fields are focused, such as optical coherence...journal article 2012

Pang, X. (author), Gbur, G. (author), Visser, T.D. (author)The phase behavior of Airy beams is studied, and their Gouy phase is defined. Analytic expressions for the idealized, infinite-energy type beam are derived. They are shown to be excellent approximations for finite-energy beams generated under typical experimental conditions.journal article 2011
