Dinâmica de vórtices em osciladores paramétricos ópticos
| Posted on: 01 out. 2004We show the main features of optical vortices with orbital angular momentum in the paraxial regime, and how to produce and characterize such beams. An outline of the parametric amplification process, in the context of an ... -
Dinâmica e ruído quântico em osciladores paramétricos óticos com momento angular orbital
| Posted on: 06 mar. 2009We shall present a description of beams bearing orbital angular momentum (OAM)in the paraxial regime, in addition to techniques showing how to produce such beams. Followed by a brief classical description of the optical ... -
Função de Wigner de dois modos amplificados em um oscilador paramétrico óptico não-degenerado
The aim of this work is to present the Wigner function of two amplified modes in an nondegenerated optical parametric oscillator which is strictly positive and convergent, characterizing a valid distribution of probability ...
