Gaussian Beam Propagation
Gaussian beams play such an important role in optical lasers as well as in longer wavelength systems that they have been extensively analyzed, starting with some of the classic treatments mentioned in Chapter 1. Almost every text on optical systems discusses Gaussian beam propagation in some detail, and several comprehensive review articles are available. However, for millimeter and submillimet...
متن کامل3D Gaussian beam modeling
The initial objective was to implement a 3D Gaussian beam model on multi-core, high-performance computing hardware in order to support mid and high frequency applications like reverberation modeling and acoustic channel simulation. As graphic processing unit or GPU hardware rapidly emerged as a compelling platform for such work, my objective became to adapt selected acoustic wave propagation mo...
متن کاملPropagation factor of a stochastic electromagnetic Gaussian Schell-model beam.
Analytical formula is derived for the propagation factor (known asM(2)-factor) of a stochastic electromagnetic Gaussian Schell-model (EGSM) beam in free space and in turbulent atmosphere. In free space, the M(2)-factor of an EGSM beam is mainly determined by its initial degree of polarization, r.m.s. widths of the spectral densities and correlation coefficients, and its value remains invariant ...

متن کاملLaser and Gaussian Beam Propagation and Transformation
Optical engineers and researchers working on optics deal with laser beams and optical systems as usual tools in their specific areas. The knowledge of the special characteristics of the propagation of laser beams through optical systems has to be one of the keystones of their actual work, and the clear definition of their characteristic parameters has an important impact in the success of the a...
