Coupling efficiency of a partially coherent laser beam from the anisotropy and non-Kolmogorov marine-atmosphere turbulence to fiber

Abstract We evaluate the parameter effects of the laser source, coupling lens and turbulence on the fiber coupling efficiency. Our results indicate that there are optimal radius of the wave-front curvature and transmitting radius of laser beam and optimal focal length of a coupling lens for specific turbulence strength and propagation distance. By utilizing the optimal wave-front curvature, optimal focal length and optimal transmitting beam radius, one can maximize the coupling efficiency.
