数值研究了惰性气体填充的空芯波导中真空紫外脉冲产生的啁啾四波混频。考虑到电离效应，我们预测产生的信号脉冲在160 nm的最短持续时间高达6.5 fs，最高脉冲能量高达mJ的水平和最大能量效率约30%的宽带啁啾闲频脉冲在800 nm和窄带泵浦脉冲在270 nm。使用级联工艺，还可以产生在90至140 nm的光谱范围内的亚10 fs脉冲。(C)2008年美国光学学会
We numerically study chirped four-wave mixing for VUV pulse generation in hollow waveguides filled with a noble gas. Taking into account ionization effects we predict the generation of signal pulses at 160 nm with shortest durations up to 6.5 fs, highest pulse energy up to the mJ level and maximum energy efficiency of about 30% by broadband chirped idler pulses at 800 nm and narrow-band pump pulses at 270 nm. Using cascaded processes sub-10-fs pulses in the spectral range from 90 to 140 nm can also be generated. (C) 2008 Optical Society of America
