Abstract
In this work, we theoretically investigate the nonlinear dynamics of a passively Q-switched Nd:YAG/Cr:YAG laser under the triangular wave pump modulation. The influence of the key parameters of the modulation frequency, modulation amplitude, and unmodulated pump rate on the nonlinear dynamics are analyzed. Meanwhile, the nonlinear dynamic evolution routes of the pulse peak and pulse frequency are also determined. The results show that the passively Q-switched Nd:YAG/Cr:YAG laser can exhibit rich nonlinear dynamics, such as period-one (P1), period-two (P2), multi-period (MP), and chaotic pulsation (CP) under some suitable parameters. Furthermore, the nonlinear dynamic evolution routes of pulse peak and pulse frequency exhibit similar trends, but their intensity changes follow opposite directions.
期刊介绍:
The IEEE Journal of Quantum Electronics is dedicated to the publication of manuscripts reporting novel experimental or theoretical results in the broad field of the science and technology of quantum electronics. The Journal comprises original contributions, both regular papers and letters, describing significant advances in the understanding of quantum electronics phenomena or the demonstration of new devices, systems, or applications. Manuscripts reporting new developments in systems and applications must emphasize quantum electronics principles or devices. The scope of JQE encompasses the generation, propagation, detection, and application of coherent electromagnetic radiation having wavelengths below one millimeter (i.e., in the submillimeter, infrared, visible, ultraviolet, etc., regions). Whether the focus of a manuscript is a quantum-electronic device or phenomenon, the critical factor in the editorial review of a manuscript is the potential impact of the results presented on continuing research in the field or on advancing the technological base of quantum electronics.
