Bifurcation analysis for CO2 laser

Abstract

The bifurcation behaviors for CO2 laser is studied using four level system model, by solving the differential equations describing that model. The bifurcation diagram gave very clear idea about dynamic behaviors. This system, it has been drawn as a function of modulation amplitude parameter A. From all this, we obtained a scenario of the diagrams by increasing frequency of modulation signal parameter ( ) within (A- ) plane. Many of different dynamic behaviors such as period doubling and chaos are observed.
