Abstract

The application of feedback to produce bistable states in a molecular system was first considered by Szoke and then extended and demonstrated by Gibbs. The final configuration is similar to a laser, having two resonator mirrors enclosing a molecular system, but with the intensity decreased. Such behavior is similar to a laser at threshold but the control variable is the electrical input and the output is the radiated beam. Video systems can also provide a simple optical feedback system. Such systems are inherently slow, and limited to video rates, however, they possess many control variables and are simple to adjust interactively. Such systems have been used and reported in the literature for image processing and for generation of optical bistable states. Here such a system lends itself readily to modeling certain aspects of laser dynamics.
