Abstract
The Bessel–Gaussian Schell-model (BGSM) beam has been proved to have an annular distant facula. In this paper, we found the radius of the halo is determined by the Bessel parameter and propagation length, rather than turbulence, which means the BGSM beams with different Bessel parameter could distinguish each other physically. we generated a BGSM beam and analyzed its scintillation index in weak atmosphere both in theory and experiment and studied its self-healing property. Compare to the GSM beam, the Bessel factor in coherence domain improves the BGSM beam in terms of scintillation index (SI). According to the mean-square error (MSE), the BGSM beam suffers the same amount of shape distortion as that of the GSM beam under blocking, both of which present excellent resistance to occlusion compared to coherent Gaussian beam. To alleviate the source-introduced optical intensity distribution, statistical average in both time domain and spatial domain was studied and presents adequate efficiency. The result indicated the BGSM beam has potential application for space-division multiplexing in free-space optical communication.
