Spreading of partially coherent beams in random media
Greg Gbur,Emil Wolf +1 more
TL;DR: This suggestion that partially coherent beams may be less susceptible to distortions caused by propagation through random media than fully coherent beams is studied quantitatively by examining the mean squared width of partially incoherent beams in such media as a function of the propagation distance.

Mode analysis of spreading of partially coherent beams propagating through atmospheric turbulence
TL;DR: It is found that in atmospheric turbulence the relative spreading of higher-order modes is smaller than that of lower- order modes, whereas the relative spread of all order modes is the same as in free space.
Journal ArticleDOI
Partially coherent beam propagation in atmospheric turbulence [invited].
TL;DR: The basic theoretical and computational tools used to investigate partially coherent beams' resistance to the deleterious effects of atmospheric turbulence are described and reviewed.

Beam propagation factor of partially coherent flat-topped beams in a turbulent atmosphere.
Youquan Dan,Bin Zhang +1 more
TL;DR: It can be shown that the M(2)-factor of PCFT beams in turbulence depends on the beam order, degree of global coherence of the source, waist width, wavelength, spatial power spectrum of the refractive index fluctuations, and propagation distance.

Propagation of laser array beams in a turbulent atmosphere
TL;DR: In this article, the average irradiance of phase-locked and non-phase-locked radial and rectangular laser array beams is derived through vector integration and tensor operation, and the irradiance properties of these laser arrays in a turbulent atmosphere are studied numerically.

Coherence and radiometry with quasihomogeneous planar sources
William H. Carter,Emil Wolf +1 more
TL;DR: In this paper, the concept of quasihomogeneous sources is introduced and an important reciprocity relation is shown to exist between light in the far zone and in the source plane, which implies that the degree of coherence in far zone is given by the classic form of the van Cittert-Zernike theorem, even though the source may have a high degree of spatial coherence over arbitrarily large areas.
Journal ArticleDOI
Theory and application of wave propagation and scattering in random media
TL;DR: A review of basic theories and recent advances in the studies of wave propagation and scattering in random media is presented in this article, where propagation characteristics of intensities, wave fluctuations, pulse propagation, and scattering, coherence bandwidth, and coherence time of communication channels through random media are analyzed.

Propagation parameters of gaussian Schell-model beams
Ari T. Friberg,Ronald J. Sudol +1 more
TL;DR: In this paper, the propagation of partially coherent light beams generated by gaussian Schell-model sources is characterized by two parameters that are analogous to the beam radius and the radius of wavefront curvature of fully coherent gaussian laser beams.

Partially coherent sources which produce the same far-field intensity distribution as a laser
Emil Wolf,E. Collett +1 more
TL;DR: In this article, it was shown that certain partially coherent model sources whose intensity distribution and degree of coherence are both gaussian will generate the same far-field intensity distributions as a completely coherent laser source.
