wave optics simulationWe recently proposed a metric that incorporates scintillation reduction and beam spread for evaluating the performance of a partially coherent laser beam propagating through atmospheric turbulence. The metric was evaluated relative to other measures such as probability of fade and ...
Gaussian Beam Propagation Note: this calculation is only valid for paraxial rays and where the thickness variation across the lens is negligable. Lens Element Beam Diameter At Optic (mm) Beam Divergence (mRad) Rayleigh Range (mm) Beam Waist Diameter (mm) Beam Waist Location (mm) Share To...
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 ...
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 ...
In this paper, a single-photon receiving efficiency model is proposed incorporating the single-photon acquisition probability and channel transmittance based on the Gaussian beam propagation. We also present simulation and experiment of beam-spot size widening through a 0.5 km free-space channel to ...
BANDWIDTH: The FWHM frequency width of the time-domain pulse. Results returned BEAM: Provides information about spatial distribution of electric (E) and magnetic (H) fields injected by the source within the limits of simulation region.
1) Create a .ZBF file which defines a super-Gaussian beam to use in Physical Optics Propagation (POP) In POP, you have several definitions for your input beam in the Beam Definition tab. One of the Beam Type options is "File," which can take in an arbitrary .ZBF format file. Using ...

As a model of the amplitude profile of the transducer, the Gaussian amplitude profile is adopted in the numerical simulation. An incident wave uin can be expressed as (10)uminx=−Fry^y^me−ikLy^⋅x where −y^ is the propagation direction of the incident wave and F(r) is the ...
