将单脉冲能量约为 2 .5nJ、脉宽为 2 5fs、对应峰值功率为 0 .1MW的的 80 0nm钛宝石激光耦合到长为10mm ,芯径为 1.8μm的光子晶体光纤中 ,产生了耦合效率约为 17%、谱宽覆盖可见光及近红外波段的超连续光谱。
The single-pulse energy of about 2.5nJ, pulse width of 25fs, the corresponding peak power of 0. 1MW of 80Onm titanium laser coupled to a length of 10mm, a diameter of 1.8μm photonic crystal fiber, resulting in a coupling The efficiency is about 17% and the spectral width covers the supercontinuum in the visible and near-infrared bands.
