由双暗态引起的窄谱线增强和双光子透明现象

原子相干和量子干涉效应正逐步成为共振非线性光学物理的一种重要而且广泛的应用工具。在光学介质的非线性光学性质的研究中,在单光子、双光子和多光子吸收的禁止方面这些效应具有潜在的应用价值。尤其在光子比较少的光学领域,我们已经观察到了由电磁诱导透明的特大Kerr非线性特征和折射率增大而引起的无吸收非线性光学,这对量子非线性光学性质的研究具有极其重要的作用。

Enhancement of Narrow Spectra and Two-photon Transparency Induced by Double-dark Resonance

Atomic coherence and quantum interference effect is gradually becoming a kind of important and widely used tool in resonance nonlinear optical physics. It should have potential application value in the non-linear optical properties and in the prohibition of single-and two-photon and absorption. Especially in the optical field which has relatively less photon,we have observed the non-absorption non-linear optics caused by the large Kerr non-linear characteristics of electromagnetically induced transparency and increase of refractive index, which plays an important role for non-linear optical properties of quantum, and opens a new field.
