Resonance, multiple diffusion and critical tunneling for Gaussian lasers

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.
