The dipole-dipole interaction between the V-type three-level atoms is shown to give rise to the Poincar\\'e-Andronov-Hopf bifurcation in steady-state solution of the equations of motion. As a result, the populations of the energy levels periodically vary in time. In the framework of the two-level model, dynamical instabilities are proved to be impossible.","authors_text":"A. M.
