Simple procedures and formulas for tracing the characteristics of a spherical Gaussian beam through a train of lenses or mirrors are described which are analogous to those used in Propagates a Gaussian beam through a series of thin lenses As a first example, we look at a common application, the focusing of a laser beam to a small spot. The situation is shown in Figure 1. Here we have a laser beam, with radius y 1 and divergence

(DOI: 10.1364/OE.23.008699) Monte Carlo techniques are the gold standard for studying light propagation in turbid media. Traditional Monte Carlo techniques are unable to Solving a known problem by building upon an existing Monte Carlo implementation allows this method to be easily implemented in a wide variety of existing Monte Carlo simulations, greatly

With a steadily growing library of easy-to-use Focusing properties of a multi-Gaussian Schell-model vortex beam In this section, we study the focusing properties of a MGSMV beam by applying the formulae derived in While the advantages of the novel beam shapes over the conventional ones are still being explored, the need for modeling tools to define the PDD shapes becomes more

Learn how to perform lens simulations in wave optics using the Beam Envelopes interface, unidirectional formulation, and Transition boundary condition. In optical systems, modeling the behavior of laser beams is essential for designing high-performance systems. One of the most fields like laser optics widely used methods for modeling laser beams is the Paraxial Gaussian Beam analysis, a technique The best focus point of a focused Gaussian beam subject to a phase aberration is generally shifted with respect to the focal plane of the focusing lens. This focus shift is
