The Lorenz-Haken system that is usually used as a model for the Helium-Neon Laser is considered. This system exhibits several types of bifurcations. The bifurcation scenarios have been studied using a mathematical package MATCONT. We have shown that the behavior of the system is sensitive to changes in parameters. We have identified several instances of Hopf and Pitchfork bifurcation at the operating point. The similar behavior is occurred when some parameters of the system are changed. The bifurcations in some cases have symmetrical nature.
