Abstract

With the aim of developing experiments for teaching dynamics of complex systems and stabilization methods in lasers, we study the dynamics of a diode-pumped Nd:YVO₄ laser under periodic loss modulation produced with an acousto-optic modulator and a function generator. Our goal is stabilization of the laser oscillations in a chosen dynamical state. The results obtained with the rate-equation model for different modulation schemes are in a good agreement with the experiments.

Keywords: Chaos on lasers; laser dynamics; Nd:YVO₄ lasers.
