Paraxial optical fields whose intensity pattern skeletons are stable caustics
Paraxial optical fields whose intensity pattern skeletons are stable caustics is a scholarly work, published in 2019 in ''Journal of the Optical Society of America''. The main subjects of the publication include mathematical analysis, classical mechanics, Laplace transform, plane wave, Laplace's equation, partial differential equation, paraxial approximation, sinusoidal plane-wave solutions of the electromagnetic wave equation, polarimetry, superposition principle, wave equation, frequency comb, mathematics, Hamilton–Jacobi equation, physics, optical tweezers, Green's function for the three-variable Laplace equation, and Caustic. The authors construct exact solutions to the paraxial wave equation in free space characterized by stable caustics.
