  Title Bohm approach to the Gouy phase shift Type
  Year 2022 Publication Optik Abbreviated Journal Optik  
  Volume 252 Issue Pages 168468  
  Keywords Gouy phase; Bohm potential; Lewis-Ermakov invariant  
  Abstract By adapting the Madelung-Bohm formalism to paraxial wave propagation we show, by using Ermakov-Lewis techniques, that the Gouy phase is related to the form of the phase chosen in order to produce a Gaussian function as a propagated field. For this, we introduce a quantum mechanical invariant, that it is explicitly time dependent. We finally show that the effective Bohm index of refraction generates a GRIN medium that produces the focusing needed for the Gouy phase.
