English: An animated render of a monochromatic, paraxial, linearly polarized Laguerre-Gaussian beam with a beam waist = 0.8 λ. The red and blue false colors indicate the intensity of the electric field with a positive and negative phase, respectively, which represents the electric field vector pointing in opposite directions. The electric field was calculated using the paraxial complex amplitude for a Laguerre-Gaussian mode with l=1 and p=0. The field was processed using MATLAB and the render was created using Blender. This was produced by Dr. Jack Kingsley-Smith at the Physics Department, Photonics & Nanotechnology Group of King's College London.
