“…[7][8][9][10]. In particular, it was shown in [7][8][9] that the dynamical gain saturation is essential for the coherent quasi-soliton generation in the lasers. However, the dynamical gain saturation is negligible in femtosecond solid-state lasers, where the dominating nonlinear factors are the self-phase modulation (SPM) and the self-focusing.…”

The results of the study of ultra-short pulse generation in continuous-wave Kerrlens mode-locked (KLM) solid-state lasers with semiconductor saturable absorbers are presented. The issues of extremely short pulse generation are addressed in the frames of the theory that accounts for the coherent nature of the absorber-pulse interaction. We developed an analytical model that bases on the coupled generalized Landau-Ginzburg laser equation and Bloch equations for a coherent absorber. We showed, that in the absence of KLM semiconductor absorber produces 2π -nonsech-pulses of self-induced transparency, while the KLM provides an extremely short sech-shaped pulse generation. 2π-and π -sech-shaped solutions and variable-area chirped pulses have been found. It was shown, that the presence of KLM removes the limitation on the minimal modulation depth in absorber. An automudulational stability and self-starting ability were analyzed, too.

The results of the study of ultra-short pulse generation in continuous-wave Kerr-lens mode-locked (KLM) solid-state lasers with semiconductor saturable absorbers are presented. The issues of extremely short pulse generation are addressed in the frames of the theory that accounts for the coherent nature of the absorber-pulse interaction. We developed an analytical model that bases on the coupled generalized Landau-Ginzburg laser equation and Bloch equations for coherent absorber. We showed, that in the absence of KLM semiconductor absorber produces 2it-non-soliton pulses of self-induced transparency, while the KLM provides an extremely short soliton generation. 2it-and itsech-shaped soliton solutions and variablesquared chirped solutions have been found. It was shown, that the presence of KLM loosens the stability requirements for ultra-short pulse generation removing the limitation on the minimal modulation depth in absorber necessary for the pulse stabilization. An automudulation stability and self-starting ability analysis is presented.
