The simulations of the system were performed using Fresnel transformations for the field propagation before and after the lens. The simulation results showed how much the beam is distorted at the output of the imaging system depending on the size of the obstacle and its distance from the ...
There exist several difficulties of existing simulation techniques for the computation of optical beams. These are the high computational amount in order to resolve the phase of the beam and modelling non゛bsorbing boundary conditions. We present a new beam propagation method, which circumvents ...
Figures below demonstrate how the center of focus for a Gaussian beam can be adjusted to any desired coordinates in the simulation. This is possible by adjusting the center of focus from "beam options" tab in source properties as is discussed further in this page. Visualization of the Ex fie...
A Gaussian beam has the highest possible beam quality, which is related to the lowest possible beam parameter product, and corresponds to M2 = 1. The fundamental propagation modes of fibers are generally not exactly Gaussian, but also not too far from that shape. Therefore, a Gaussian beam ...

By using the average intensity formula, some numerical simulation comparisons are made and some special cases are studied, especially the influences of the ChG beam parameter (Ω 0 ), the propagation distance, the aperture and its size on the average normalized intensity distribution. It is ...
In this paper, the feature of the propagation and transformation of Gaussian beam through an optical system is analysed detailedly on the bassis of the ABCD law of Gaussian beam in terms of Gaussian Brackets. Then, a variety of typically optical systems or some special eases are discussed deepl...
