Development of wideband highly functional mono-cycle optical frequency comb source using ultrafast nonlinear optical effect

在这项工作中，我们研究了利用非线性光纤效应的高功能超短脉冲源。首先，对碳纳米管超短脉冲光纤激光器进行了数值分析。结合数值结果，我们成功地演示了285mw最高功率的碳纳米管光纤激光器。其次，介绍了利用所研制的纳米管光纤激光器的光频梳系统。然后，利用相似光纤放大器成功地产生了50 fs的高功率超短脉冲，并产生了一个跨倍频相干超连续谱。最后，利用X-FROG首次观测到了产生的相干超连续谱图。

In this work, we investigated highly functional ultrashort pulse source using nonlinear fiber effects. First, we demonstrated numerical analysis of ultrashort pulse fiber laser using carbon nanotube. Considering the numerical results, we succeeded in the demonstration of 285 mW highest power fiber laser using carbon nanotube. Next, optical frequency comb system using developed nanotube fiber laser was demonstrated. Then, 50 fs high power ultrashort pulse was successfully generated using similariton fiber amplifier, and an octave spanning coherent supercontinuum was generated. Finally, the spectrogram of generated coherent supercontinuum was ob served using X-FROG for the first time.
