A research of the coherent radiation generated through an interaction between two dimensional atomic clusters and high intensity laser

本研究的主要目的是利用碳纳米管与高强度激光场的相互作用产生高功率太赫兹辐射。在第一年，我们购买了一个用于合成单壁碳纳米管（SWCNT）的反应室。该实验室用于确定合成的最佳条件，如底物材料或表面催化剂。得到了一种周期性排列单壁碳纳米管的方法。同时，通过计算机模拟分析了碳纳米管与高功率激光场的相互作用。结果表明，二次谐波激光与基频激光同时照射可以激发出低频模式。

The main purpose of this research is the generation of high power terahertz radiation from an interaction between carbon nanotubes and high intensity laser field. In the first year, we purchased a reaction chamber which is designed to synthesize single walled carbon nanotubes(SWCNT). This chamber has been used to determine the optimum conditions for the synthesis such as substrate material or surface catalysts. As a result, we obtained a method to arrange SWCNT periodically. At the same time, we have analyzed an interaction between carbon nanotubes and high power laser field through a computer simulation. As a result, it is found that the low frequency mode can be excited by the irradiation of a second harmonic laser with a fundamental lasersimultaneously.
