Possible appearance of quasiperiodic and chaotic self‐pulsations in a system of coherent excitons and photons as well as in the processes of one‐ and two‐photon exciton–biexciton conversions are established for the first time. In the last two cases the generalized Lorenz equations are obtained. Lyapunov analysis of the stationary state stability and computer experiments are made. The main bifurcations in the three considered systems of quasiparticles are found.
