Coherent and partially coherent CW laser beam propagation in lens-like media: a diffractive ray-theoretic approach

The wave-kinetic method, a technique developed recently by Tappert and Besieris¹⁻³ or extending conventional ray-tracing methods to incorporate diffractive, refractive, and stochastic effects associated with the propagation of beamed signals, is illustrated in this thesis by considering the propagat...
