Abstract The interaction of ultrashort pulses with a two-level saturable absorber is considered in the colliding-pulse regime. The shortening of the Gaussian pulse duration is investigated for a wide range of absorber and pulse parameters and compared with typical contacting-absorber and non-contacting-absorber methods. The analysis of the maximum pulse dynamics taking into account the noise radiation in the context of the fluctuation model shows that in addition to the well-known advantages realized in dye lasers, the colliding-pulse method results in the achievement of shorter durations of the peak pulses in the train near the second threshold. This advantage is shown, both theoretically and experimentally, to be greater for faster the relaxation of the absorber.
