Spatiotemporal Stabilization of Turbulence-Distorted Gaussian Beams via Waveguide Spatial Filtering
Shouvik Sadhukhan, C. S. Narayanamurthy
Optical beams propagating through atmospheric turbulence undergo spatiotemporal intensity fluctuations that deviate significantly from an ideal Gaussian profile. In this work, we p…
Vectorial Control of Scintillation in Kolmogorov Turbulence and Quality Parametrization
Shouvik Sadhukhan, Shirsendu Sarkar, C. S. Narayanamurthy +1
Intensity scintillation limits free-space optical links in strong turbulence. We examine experimentally how sequential linear polarization filtering modifies the scintillation of a…
Conventional Scintillation Statistics with Turbulence Impacted Coupled Dipole Oscillation
Shouvik Sadhukhan, C. S. Narayanamurthy
We investigate the propagation of optical fields through polymethyl methacrylate (PMMA) rods under atmospheric turbulence conditions, employing a generalized Lorentz dipole oscilla…
Turbulence Impacted Wavefront Corrections Using Beam Modulation Technique
Shouvik Sadhukhan, C. S. Narayanamurthy
New experimental technique have been proposed to discuss the turbulence impact reduction using beam shaping technique. In first phase of experiments, turbulence Impacted Vortex bea…
Turbulence Impacted Beam Statistics and Image Topology with Lorentz Dipole Oscillation
Shouvik Sadhukhan, C. S. Narayanamurthy
This work presents a rigorous statistical and geometric framework for analyzing turbulence-impacted beam propagation and image topology with results obtained using a PMMA slab. The…
Coupled Dipole Oscillation Enabled Scintillation Compensation in Turbulence-Impacted Laser Beam
Shouvik Sadhukhan, C. S. Narayanamurthy
The present work develops a rigorous framework for collective dipole oscillations in dense dielectric media by extending the Lorentz oscillator model to include both quadratic (sec…
