报道了类似于1mJ 30ps的脉冲在填充Ar的空芯光子晶体光纤中传输时的光谱展宽。与在实芯光子晶体光纤中产生超连续谱相比，由于没有拉曼效应和独特的压控色散，在深紫外区产生了高效的色散波。紫外光以单瓣基模形式出现，可通过改变脉冲能量和气体压力从200 nm调谐到320 nm。设置非常简单，包括
We report on the spectral broadening of similar to 1 mu J 30 fs pulses propagating in an Ar-filled hollow-core photonic crystal fiber. In contrast with supercontinuum generation in a solid-core photonic crystal fiber, the absence of Raman and unique pressure-controlled dispersion results in efficient emission of dispersive waves in the deep-UV region. The UV light emerges in the single-lobed fundamental mode and is tunable from 200 to 320 nm by varying the pulse energy and gas pressure. The setup is extremely simple, involving
