Application of Cellular Automata Algorithms to the Parallel Simulation of Laser Dynamics
(John Wiley & Sons, Inc., 2008) Guisado Lizar, José Luis; Jiménez Morales, Francisco; Guerra, J.M.; Fernández, F.; Universidad de Sevilla. Departamento de Arquitectura y Tecnología de Computadores
In this chapter we review the use of a biologically inspired heuristic technique— cellular automata (CA)—as a problem solver for one of the most paradigmatic complex systems: the laser. CAs are a class of mathematical system that can be used to model spatiotemporal phenomena, characterized by the discreteness of all of its variables: space, time, and normally state variables. An important property of CAs is their intrinsic parallel character. Therefore, they are specially well suited to be implemented very efficiently on parallel computers.
Simulating Laser Dynamics with Cellular Automata
(Springer Verlag, 2018) Jiménez Morales, Francisco; Guisado Lizar, José Luis; Guerra, José Manuel; Universidad de Sevilla. Departamento de Arquitectura y Tecnología de Computadores
The long-established approach to study laser dynamics uses a set of differential equations known as the laser rate equations. In this work we present an overview of an alternative model based on a cellular automaton (CA). We also present a panorama of different variants of the model: the original one, designed to simulate general laser dynamics; an additional one, that was proposed to simulate pulsed pumped lasers; and finally a new model to simulate lasers that exhibit antiphase dynamics, which is proposed here. Despite its simplicity, the CA model reproduces qualitatively the phenomenology encountered in many real laser systems: (i) the existence of a threshold value of the pumping rate Rt;(ii)the exact dependence of Rt on the life times of the photons and the inversion population; (iii) the two main laser regimes: a steady state and an oscillatory one
