在空心熔融石英光纤的基横模中，获得了强度约为（1 - 2）× 10 ~（15）W/cm ~ 2的亚10飞秒激光脉冲。熔融石英在低于10-fs的制度下的高抗损伤性允许稳定的可再现操作，而不会使毛细管波导退化。在初步的实验中，我们展示了千赫重复率导波高谐波产生氦下降到10 nm的范围。报道的实验开辟了在良好控制的条件下实现强度水平超过10（15）W/cm（2）的平面波激发的高场相互作用的途径。
Sub-10-fs laser pulses have been guided in the fundamental transverse mode of a hollow-core fused-silica fiber at intensities of approximate to (1 - 2) x 10(15) W/cm(2). The high resistance of fused silica to damage in the sub-10-fs regime allows stable reproducible operation without degradation of the capillary waveguide. In preliminary experiments, we demonstrate kHz-repetition-rate guided-wave high-harmonic generation in helium down to the 10-nm range. The reported experiments open up the way to realizing high-field interactions with plane-wave excitation at intensity levels in excess of 10(15) W/cm(2) under well-controlled conditions.
