论文摘要
非线性光学器件一直是一个非常动态的研究领域，主要在激光发明后发现了壮观的现象。高强度场与共振系统的结合进一步增强了非线性，并与与共振相关的特定其他效果。在本文中，我们回顾了这些效果有限的范围，在过去的几十年中，使用近距离的原子蒸气作为非线性谐振培养基进行了研究。特别是我们描述了四波混合（4WM）和原子蒸气中的非经典光。讨论了一个和两种模式挤压以及光子相关性。此外，我们为基于热原子蒸气的光学和量子记忆提供了一些应用。最后，我们介绍了使用热原子蒸气的最近开发的光量流体领域的结果。
Nonlinear optics has been a very dynamic field of research with spectacular phenomena discovered mainly after the invention of lasers. The combination of high intensity fields with resonant systems has further enhanced the nonlinearity with specific additional effects related to the resonances. In this paper we review a limited range of these effects which has been studied in the past decades using close-to-room-temperature atomic vapors as the nonlinear resonant medium. In particular we describe four-wave mixing (4WM) and generation of nonclassical light in atomic vapors. One-and two-mode squeezing as well as photon correlations are discussed. Furthermore, we present some applications for optical and quantum memories based on hot atomic vapors. Finally, we present results on the recently developed field of quantum fluids of light using hot atomic vapors.
