Polarization-induced reduction in scintillation of optical beams propagating in simulated turbulent atmospheric channels

Abstract

It is experimentally demonstrated that the class of partially coherent, partially polarized optical beams can be efficiently used for reduction in scintillations on propagation through turbulent air. The experiment involving the electromagnetic beam generation and its interaction with turbulent air simulator is discussed in details. The collected data is in solid agreement with the recently published theoretical predictions.

Effect of the atmospheric turbulence on a special correlated radially polarized beam on propagation

“…In general, the atmospheric turbulence will cause the extra spreading beyond the diffraction, wander and scintillation of laser beams, which limits the performance in the previously mentioned applications. Thus, knowledge of the propagation behavior of light beams in atmospheric turbulence is utmost significant [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34]. It is known that decreasing spatial coherence and modulating polarization distribution of light beams are two effective methods to reduce the turbulence-induced degradation.…”

Generation of Vector Partially Coherent Optical Sources Using Phase-Only Spatial Light Modulators

“…Their widespread appeal stems from the fact that, by simply manipulating spatial coherence, the source's resulting shape and polarization can be precisely controlled. Numerous researchers have designed vector partially coherent sources for applications such as free-space and underwater optical communications [7][8][9][10][11][12][13][14][15][16], remote sensing [17,18], optical scattering [19][20][21][22][23][24][25][26][27][28][29], and particle manipulation and trapping [30][31][32][33].…”

Phase-only implementation of the complex screen technique for generating schell-model sources

“…The behavior of partially-coherent light has been the subject of extensive research especially in the last 10 years. Numerous theoretical and some experimental studies have been performed examining how partially-coherent light propagates through free space and random media (atmospheric turbulence, biological tissue, and ocean water) [1][2][3][4][5] and scatters from deterministic and random objects [6][7][8][9][10]. These studies, as well as many others, have noted interesting characteristics of partially-coherent light that can possibly be exploited in applications such as free-space optical communications, directed energy, remote sensing, particle manipulation, and etcetera.…”
