TLDR
In this paper, an analytical expression for mode-conversion coefficients at a laser-air interface is derived using plane-wave decomposition of the modal fields and the radiation pattern is explicitly expressed as function of Fresnel reflection coefficients of the interface and the incident mode spectrum.Abstract:
An analytical expression for mode-conversion coefficients at a laser–air interface is derived using plane-wave decomposition of the modal fields. Both the mode-conversion coefficients and the radiation pattern are explicitly expressed as function of Fresnel reflection coefficients of the interface and the incident mode spectrum.read more
