In this paper, the propagation of electromagnetic pulse in the medium of single-walled carbon nanotubes (chiral type) is investigated. The existence of the second harmonic generation mode, which was not observed at the initial time, is revealed. A high second harmonic output is set, as well as the dependence of the second harmonic output on the problem parameters. It is proposed to use this effect to generate entangled photons.

在具有手性碳纳米管的介质中传播极短光脉冲期间二次谐波的产生

本文研究了电磁脉冲在单壁碳纳米管（手性型）介质中的传播。揭示了初始时未观察到的二次谐波生成模式的存在。设置高二次谐波输出，以及二次谐波输出对问题参数的依赖性。有人提议利用这种效应来产生纠缠光子。
