| Abstract: | Atmospheric turbulence induced intensity fluctuations lead to scintillation,beam drift,angle of arrival fluctuation and wavefront aberration.The multi-beam launch technique is one of the effective ways to mitigate the effect of atmospheric turbulence.Calculation of the beam quality parameters through peak intensity,encircled power radius and bulk parameters based on single beam,double beam,four beam and eight beams of light emission was made.Single-beam and multi-beam intensity fluctuation characteristics o... |
