Abstract

This study investigates the changes of the threshold of chaotic behavior in a pump-modulation Nd:YVO4 laser created by varying the shape of the modulation profile. The threshold for chaotic behavior can be increased and decreased when the modulation profiles are reshaped by triangular wave and Jacobi elliptic sine functions, respectively. Experimental results show that sinusoidal-wave, square-wave, and triangular-wave modulations have different chaotic thresholds, agreeing with numerical results. In addition to the dynamic parameters of modulation frequency and modulation depth, the shape of modulation is an important parameter for controlling the nonlinear dynamics in pump-modulation lasers.
