摘要：

Third-harmonic generation in a hollow glass fiber has been demonstrated. Ti:sapphire laser pulses 100 fs with a moderate intensity of around 1x10(14)W/cm(2) are introduced into a 1.8-cm hollow fiber in room air. From the observation of the third-harmonic beam quality and spectra, it is clarified that the harmonics are pumped at the leading edge of the fundamental pulse. The model calculation accounting for the nonlinear refractive index change of air shows a quantitative agreement with the experimental results.
