Development of two-color synchronized ultrashort pulse fiber laser using trapped pulse amplification

本文利用双折射光纤中的捕获脉冲放大技术，研究了被动同步双色超短脉冲光纤激光器。首先，对捕获脉冲放大特性进行了数值和实验研究。成功地证实了ASE噪声产生相干超短脉冲。然后，研制了以碳纳米管为泵浦脉冲源的超短脉冲光纤激光器。所研制的光纤激光器结合了一个附加腔，并证实了光脉冲放大。在已开发的空腔中，数值证实了双色同步脉冲振荡。期望利用腔稳定技术实现双色同步脉冲激光器。

In this work, we investigated passively synchronized two color ultrashort pulse fiber laser using trapped pulse amplification in birefringent fibers. First, the characteristics of trapped pulse amplification were investigated both numerically and experimentally. The coherent ultrashort pulse generation from ASE noise was successfullyconfirmed. Then, an ultrashort pulse fiber laser using carbon nanotube was developed as pump pulse source. An additional cavity was combined with the developed fiber laser and optical pulse amplification was confirmed. In the developed cavity, two color synchronized pulse oscillation was confirmed numerically. It is expected that the two color synchronized pulse laser would be demonstrated using the cavity stabilization technique.
