Experimental Evidence of Subharmonic Bifurcations, Multistability, and Turbulence in a Q -Switched Gas Laser

Subharmonic bifurcations, generalized multistability, and chaotic behavior were found experimentally in a Q-switched CO2 laser operating at 10.6 micrometers. Jumps between two strange attractors lead to a low-frequency (1/f type) divergence in the power spectrum. This is the first experimental evide...

Description
Summary:Subharmonic bifurcations, generalized multistability, and chaotic behavior were found experimentally in a Q-switched CO2 laser operating at 10.6 micrometers. Jumps between two strange attractors lead to a low-frequency (1/f type) divergence in the power spectrum. This is the first experimental evidence of these phenomena in a quantum-optical molecular system. A theoretical model is also presented whose results are in good agreement with the experimental data.
