摘要: An analysis is made of the propagation ultrashort pulses in a fibre waveguide doped with resonant impurities. Equations describing evolution pulse case one-photon and two-photon resonances are derived on condition that Rabi frequency considerably less than detuning from an exact resonance. The influence impurity atoms parameters characteristics its (ultrashort duration, 'soliton threshold', collapse threshold) determined. corrections to these quantities have different signs for types
