    "abstract": "The results of the study of ultra-short pulse generation in continuous-wave\nKerr-lens mode-locked (KLM) solid-state lasers with semiconductor saturable\nabsorbers are presented. The issues of extremely short pulse generation are\naddressed in the frames of the theory that accounts for the coherent nature of\nthe absorber-pulse interaction. We developed an analytical model that bases on\nthe coupled generalized Landau-Ginzburg laser equation and Bloch equations for\na coherent absorber. We showed, that in the absence of KLM semiconductor\nabsorber produces 2pi - non-sech-pulses of self-induced transparency, while the\nKLM provides an extremely short sech-shaped pulse generation. 2pi- and\npi-sech-shaped solutions and variable-area chirped pulses have been found. It\nwas shown, that the presence of KLM removes the limitation on the minimal\nmodulation depth in absorber. An automudulational stability and self-starting\nability were analyzed, too.",
