Abstract.
The phase-matching process of high-order harmonics generated in rare gases confined in a hollow-fiber wave-guide is investigated theoretically. A simple calculation is built to explore the effects of several important parameters in phase-matched high-order harmonics generation. A cutoff intensity for a certain order phase-matched harmonic is found, which depends on the maximum order of phase-matched harmonic. The calculations show that an ultrashort laser pulse and the medium with a higher ionization potential are necessary for generation of higher-order phase-matched harmonics.
