Laser Gaussian beam divergence depending on random phase distortions of the field

The focused laser beam divergence with random phase distortions of the field was theoretically investigated. In the original model, radiation as the sum of two statistically independent terms: deterministic and random with zero average statistical value was represented. Relations for calculating the...

Description
Summary:The focused laser beam divergence with random phase distortions of the field was theoretically investigated. In the original model, radiation as the sum of two statistically independent terms: deterministic and random with zero average statistical value was represented. Relations for calculating the beam divergence depending on the statistical characteristics of the phase distortions of the field are obtained.
