Experimental evidence of laser power oscillations induced by the relative Fresnel (Goos-Haenchen) phase
S. A. Carvalho, S. De Leo, J. A. O. Huguenin +2
The amplification of the relative Fresnel (Goos-Haenchen) phase by an appropriate number of total internal reflections and the choice of favorable incidence angles allow to observe…
The effect of the geometrical optical phase on the propagation of Hermite-Gaussian beams through transversal and parallel dielectric blocks
Silvania A. Carvalho, Stefano De Leo
When an optical beam propagates through dielectric blocks, its optical phase is responsible for the path of the beam. In particular, the first order Taylor expansion of the geometr…
Experimental confirmation of the transversal symmetry breaking in laser profiles
Silvânia A. Carvalho, Stefano De Leo, José A. Oliveira-Huguenin +1
The Snell phase effects on the propagation of optical beams through dielectric blocks have been matter of recent theoretical studies. The effects of this phase on the laser profile…
Weak measurement og the composite Goo-Haenchen shift in the critical region
Octavio J. S. Santana, Silvania A. Carvalho, Stefano De Leo +1
By using a weak measurement technique, we investigated the interplay between the angular and lateral Goos-Haenchen shift of a focused He-Ne laser beam for incidence near the criti…
The use of the stationary phase method as a mathematical tool to determine the path of optical beams
Silvânia A. Carvalho, Stefano De Leo
We use the stationary phase method to determine the path of optical beams which propagate through a dielectric block. In the presence of partial internal reflection, we recover the…
Maximal breaking of symmetry at critical angle and closed form expression for angular deviations of the Snell law
Manoel P. Araújo, Silvânia A. Carvalho, Stefano De Leo
A detailed analysis of the propagation of laser gaussian beams at critical angles shows in which conditions it is possible to maximize the breaking of symmetry in the angular distr…
