Abstract

This reports out studies of dynamics and bifurcation in a NH3 laser using Zeghlach-Mandel model. We analyse theoretically dynamics stability of the laser in the three stable state using the eigenvalue equation, and give numerical discussions of dynamics stability of the laser in the three stable state using the eigenvalue. We find that there is the exponential contraction of the phase space volume element of the laser. The dynamical evolvement starting at a stable state through a periodic bifurcation to chaos is analyzed via the bifurcation diagram to give a path to chaos through quasi-periodic bifurcation scenario with different starting values. Numerical bifurcation diagram exhibits quasi-periodic bifurcation from a stable state by adjusting the pump rates. It can be clearly found that the laser moves around its unmovement points and is eventually attracted to one of the points, and it is sensitive to the initial value. The chaotic region and quasi-periodic bifurcation region are found. The movement orbits of a stationary state, quasi-period, and chaos are numerically exhibited to show rich nonlinear dynamic behaviors. The laser gives an important value to study laser systems, chaotic optics emitters, random optics signal generators, precision optics measuring devices, and optic encoding communications.
