Reconstructing the Spatial Parameters of a Laser Beam Using the Transport-of-Intensity Equation

Michael Kovalev et al.

Summary: A simple method is proposed for reconstructing the spatial parameters of a laser beam based on the transport-of-intensity equation. The method involves registering the cross-section intensity distributions in multiple planes using a single CMOS camera and then processing the experimental measurements with specialized software to reconstruct all the spatial parameters.

Relevance of longitudinal fields of paraxial optical vortices

Kayn A. Forbes et al.

Summary: Longitudinal electromagnetic fields become comparable with transverse components in strongly focused, non-paraxial beams. The angular momentum properties of paraxial optical vortex modes produce longitudinal fields that must be considered. Derivation and numerical study of first-order longitudinal components of quantized Laguerre-Gaussian modes highlight light-matter and spin-orbit interactions from longitudinal fields of paraxial beams in free space. New restrictions are placed on neglecting longitudinal fields for paraxial optical vortices interacting with atoms, molecules and nanostructures.

Diffractive Guiding of Waves by a Periodic Array of Slits

Dror Weisman et al.

Summary: The study demonstrates that waves can be guided by periodically truncating their edges, leading to repeated propagation patterns between the slits. Experimental results confirm this phenomenon for plasmonic waves on a metal-air interface and surface gravity water waves. This guiding concept is applicable to a wide variety of waves.

Experimental estimation of the longitudinal component of a highly focused electromagnetic field

David Maluenda et al.

Summary: The paper presents a relatively simple method for estimating and visualizing the longitudinal component of a highly focused electromagnetic beam, by measuring the transverse components and using Gauss's theorem. Experimental results show excellent agreement with theoretical predictions.
