Abstract

Results of the investigation of the semiclassical equations for the running wave in the laser with a saturable absorber are proposed on the basis of the system for normalized values and sizeless coordinates Here and e_i, φ_i and p_i, ψ_i are the amplitudes and phases of the field and of the polarization of the medium, accordingly, k_i is the relative inversion of populations, i=1 for an active medium, i=2 for an absorber. Constants d_i and g_i determine the relaxation rates of the inversion of populations and polarization of the medium, f_i. characterizes the distributed losses, a_i, b_i and h give the efficiency of the interaction of the polarization and inversion of the medium with the field, w_c and w_ai are the frequencies of the cavity and of the medium.
