摘要

在这项研究中，我们使用飞秒Nd:玻璃激光器的五次谐波在氢化SMF-28光纤中制造长周期光纤光栅(LPFG)。在这种情况下，双量子激发的总激发能达到11.7 eV左右，明显高于掺ge石英的带隙能值7.1 eV

Inscription of long-period fibre gratings by high-intensity femtosecond radiation at 211 nm

In this study we used the fifth harmonic of a femtosecond Nd:glass laser for long-period fibre gratings (LPFG) fabrication in a hydrogenated SMF-28 fibre. In this case, the total excitation energy of two-quantum excitation reaches the value of about 11.7 eV, which is significantly higher than the bandgap energy value of 7.1 eV for Ge-doped fused silica
