The lasing regimes of a diode laser with an external mirror are studied using the Lang - Kobayashi (LK) equations in the limit of a small distance from the mirror. The system of LK equations is integrated directly with the help of a program package developed. In addition, the instability and bifurcation points of solutions are found by calculating numerically the contour integral and the spectrum of Lyapunov exponents is calculated. The hysteresis zones of the lasing dynamics are found, which appear when the phase of a reflected signal changes. The parameters are determined at which two or three attractors corresponding to different dynamic regimes coexist in the phase space. It is shown that, when the rest of parameters are fixed, an increase in the pump power leads to a chaotic regime according to a classical scenario via period-doubling bifurcations. The regions of parameters are found in which packets of regular pulsations are generated, and the transition of these packets to the chaotic regime is observed. (lasers, active media)
