Experimental Implementation of a Laser Model with Cavity Loss Modulation

Experimental evidence of chaos and generalized multistability in a laser model with cavity loss modulation was first found in 1982, and recently revisited in a theoretical framework. Here we propose and investigate an electronic implementation of such laser model. Although a chaotic behavior has not been observed yet, the analysis provides insights in the difficulties of an experimental implementation of the model. These difficulties appear to be mainly due to the laser intensity, indeed a non-negative quantity, being simulated by a voltage, which can take on both positive and negative values.
