论文摘要
使用共同传播和反传播光束几何形状研究了使用两个激光束进行极化控制的方案。特别是,我们表明,在某些条件下,两个激光束有可能交换其极化状态。提出了一个更现实的2D传播几何形状的模型。 2D模型产生的结果截然不同(与1D传播几何形状相比),在现实环境中实现极化控制造成了困难。提出了通过将非线性光学介质减少到薄板来克服这些困难的建议。
A scheme for polarization control using two laser beams in a non-linear optical medium is studied using both co- and counter-propagating beam geometries. In particular, we show that under certain conditions it is possible for two laser beams to exchange their polarization states. A model accounting for a more realistic, 2D propagation geometry is presented. The 2D model produces drastically different results (compared to the 1D propagation geometry), creating difficulties for implementing polarization control in a realistic setting. A proposal for overcoming these difficulties by reducing the non-linear optical medium to a thin slab is presented.
