Resonance, multiple diffusion and critical tunneling for Gaussian lasers

TL;DR

This paper explores the propagation of Gaussian lasers through dielectric prisms, examining resonance, diffusion, and tunneling phenomena, and how these behaviors transition between wave-like and particle-like properties.

Contribution

It provides a detailed numerical analysis of Gaussian laser behavior in dielectric systems, highlighting the transition between coherence regimes and tunneling at critical angles.

Findings

Resonance phenomena observed in wave-like coherence regime

Multiple diffusion occurs in decoherence (particle-like) regime

Tunneling effects analyzed at critical angles

Abstract

We present a detailed study of the gaussian laser propagation through a dielectric system composed by two right angle prisms. We investigate the transition between the spatial coherence limit, which exhibits wave-like properties and for which the resonance phenomenon can be seen, and the decoherence limit, which exhibits particle-like properties and for which the multiple diffusion occurs. We also analyze the tunneling at critical angles. In our numerical analysis, we shall use BK7 and Fused Silica prisms and a gaussian He-Ne laser with a wavelength of 632.8 nm and beam waists of 2 mm and 200 micron.
