Abstract

A derivation of an analytical expression for the mode-coherence coefficients
of uniform-distributed wave propagating within different homogeneous media – as
in case of hyperbolic Gaussian beams – was presented and a simple method of
superposition of two such beams was proposed. The results obtained from this
work are highly-qualitative applicable in study and analysis of the propagation of
Hermite-Gaussian beams especially in the problems of radiation-matter interaction
and propagation of laser beam employed in modern free-space and fiber optical
communications.
