Intensity properties of partially coherent beam waves

Applied Optics, 1980
The extended Huygens-Fresnel principle is used to investigate the lateral coherence and the average on-axis intensity of partially coherent beam waves propagating in the turbulent atmosphere. A factor that determines the shift of the focal point toward the source when a beam wave propagates in turbulence is calculated.

Partially coherent beam propagation methods

Conference on Lasers and Electro-Optics, 1985
A new field of optics, appropriately called tunabte coherence optics, is finding an increasing number of applications in optical research and industry, for example, speckle reduction, apodization with partially coherent light, linewidth measurements in microdensitometry, optical projection lithography, and laser scanning, However, progress in tunabte ...

Average characteristics of partially coherent electromagnetic beams

Journal of the Optical Society of America A, 2000
Average characteristics of partially coherent electromagnetic beams are treated with the paraxial approximation. Azimuthally or radially polarized, azimuthally symmetric beams and linearly polarized dipolar beams are used as examples. The change in the mean squared width of the beam from its value at the location of the beam waist is found to be ...

Thermodynamic Entropy of Partially Coherent Light Beams

Journal of the Physical Society of Japan, 1964
The thermodynamic entropy of partially coherent light beams, as shown by M. von Laue, is given by the sum of the entropy of the principal waves, which represent the given light beams and are statistically independent of each other. The principal waves and their intensities are respectively the eigenfunctions and eigenvalues of the mutual intensity ...

Coherent and partially coherent vortex beams in turbulence

Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007
The evolution of the scintillation and topological charge of coherent and partially coherent vortex beams in turbulence is analyzed. The possibility of using such beams in optical communications is discussed.
