长锥区光子晶体光纤实现300W高功率可见光超连续谱输出

300 W high power supercontinuum generation of complete visible spectrum by long tapered photonic crystal fiber

基于小芯径、大占空比、纤芯渐变的长锥区光子晶体光纤搭建了全光纤超连续谱产生系统。使用高功率皮秒种子源泵浦,实现了314.7 W的高功率可见光超连续谱输出,光谱覆盖388~2400 nm。同时兼顾了输出高功率及短波方向的蓝移增强,是国内外公开报道的覆盖可见光的超连续谱的最高功率。

An all-fiber supercontinuum generation system is built based on a long tapered photonic crystal fiber with small core diameter, large duty cycle and gragual core change. The system uses high power picoseconds seed source pumping to achieve 314.7 W high power supercontinuum output covering all visible light with spectrum coverage 388-2400 nm. It takes into account high power and blue shift enhancement in the shortwave direction at the same time, and it has the highest power of supercontinuum covering full visible spectrum publicly reported at home and abroad.
