Development of widely wavelength tunable ultrashort pulse source in visible region using pulse trapping

本课题首先利用光子晶体光纤和超短脉冲光纤激光器系统研制了一种实用的覆盖整个可见光区的超宽带光源。其次，首次利用脉冲俘获现象实现了可见光脉冲的全光控制。在此基础上，研制了超快波长可调谐脉冲光源，并实现了准宽带光源的产生。使用所开发的光源展示了100分辨率的横截面成像。

In this project, first of all, a practical ultra wideband light source covering whole visible region was developed using photonic crystal fibers and ultrashort pulse fiber laser system. Next, the all optical control of visible pulse was demonstrated for the first time using novel phenomenon of pulse trapping. Then, an ultrafast wavelength tunable pulse source was developed and quasi-wideband light source generation was demonstrated. The ultrahigh resolution cross-sectional imaging was demonstrated using the developed light source.
