论文摘要
我们通过创建宽阔的振动拉曼频率梳子，通过旋转拉曼散射或光学的kerr效应，通过创建宽阔的振动拉曼频率梳子，展示了在充满气体核心抗谐振纤维中产生超脑产生的途径。我们的演示实验是在充满氮的纤维中利用20 ps持续时间的单个泵脉冲，产生了从440 nm到1200 nm的超脑，并具有从250 nm到360 nm的额外的深紫外线连续性。数值结果表明，这种方法可以产生从紫外线延伸到中红外的更广泛的超脑光谱。
We demonstrate a route to supercontinuum generation in gas-filled hollow-core anti-resonant fibers through the creation of a broad vibrational Raman frequency comb followed by continuous broadening and merging of the comb lines through either rotational Raman scattering or the optical Kerr effect. Our demonstration experiments, utilizing a single pump pulse with 20 ps duration at 532 nm in a nitrogen-filled fiber, produce a supercontinuum spanning from 440 nm to 1200 nm, with an additional deep ultraviolet continuum from 250 nm to 360 nm. Numerical results suggest that this approach can produce even broader supercontinuum spectra extending from the ultraviolet to mid-infrared.
