Annotation
Simple expressions for the estimation of the gas pressure allowing thirdharmonic generation in leaky modes of a hollow fiber to be phase matched and permitting optimal sizes of a hollow fiber for ultrashort-pulse generation to be chosen are derived. The enhancement of harmonic-generation efficiency in a hollow fiber relative to harmonics generation in a free gas is estimated.
