Optical fiber nonlinearity
WebAfter starting intravenous sedation and injecting a local anesthetic, physicians will insert a small catheter to deliver a tiny optical fiber, the laser and a cooling device into the … Nonlinear effects fall into two qualitatively different categories, parametric and non-parametric effects. A parametric non-linearity is an interaction in which the quantum state of the nonlinear material is not changed by the interaction with the optical field. As a consequence of this, the process is "instantaneous". Energy and momentum are conserved in the optical field, making phase match…
