非线性光学的高斯光束传播理论:轨道Angular Momentum转移的精确处理

Gaussian Beam-Propagation Theory for Nonlinear Optics - Featuring an Exact Treatment of Orbital Angular Momentum Transfer

R. Nicholas Lanning, Zhihao Xiao, Mi Zhang, Irina Novikova, Eugeniy Mikhailov, Jonathan P. Dowling

摘要:

我们提出了一个一般的,高斯空间模式的传输形式主义,用于描述在非线性相互作用过程中产生的高阶多空间模式光束的产生。此外,为了实现理论,我们模拟光学角动量转移相互作用,并显示如何可以优化的相互作用,以减少不需要的模式。过去对这个问题的理论处理充其量也只是现象学的。在这里,我们提出了一个精确的解决方案,单程无腔制度,其中的非线性相互作用不是太强。我们将我们的理论应用于两个实验,具有很好的一致性,并给出了几个配置的例子,很容易在实验室中测试。

英文摘要:

We present a general, Gaussian spatial mode propagation formalism for describing the generation of higher order multi-spatial-mode beams generated during nonlinear interactions. Furthermore, to implement the theory, we simulate optical angular momentum transfer interactions, and show how one can optimize the interaction to reduce the undesired modes. Past theoretical treatments of this problem have often been phenomenological, at best. Here we present an exact solution for the single-pass no-cavity regime, in which the the nonlinear interaction is not overly strong. We apply our theory to two experiments, with very good agreement, and give examples of several more configurations, easily tested in the laboratory.
