Paper Abstract

Carbon-dioxide lasers are well-known example of optical systems, which can exhibit complex transitions from the CW to the chaotic regime in the intensity caused by the modulation of various systems parameters. They can demonstrate classical bifurcation scenarios with period doubling, bistability, and chaotic attractors. We report on a new method of observing chaos in carbon-dioxide lasers where the simple technique of modulation of the optical feedback parameters is applied. In this approach the parameters of the carbon-dioxide laser itself remain unchanged and modulation is carried out externally. This leads to a system which can be easily assembled and studied in a graduate laboratory. Experimental results show the presence of stable periodic orbits of different periods, bistability of periodic orbits and chaotic attractors with complex transition scenarios, providing a wealth of examples for the student to investigate.
