Abstract

Self-

Q

-switching facilitates the generation of pulsed lasers without resorting to conventional

Q

-switched techniques, while there has been limited research and theoretical development in this area. In this paper, we introduce an interference-based self-

Q

-switching phenomenon and conduct a comprehensive numerical analysis. Our findings reveal distinct properties when compared to traditional

Q

-switching, underscoring the role of interferometers. Through a combination of experimental measurements and waveguide simulations, we propose a self-

Q

-switching mechanism based on jitter-induced filtering. This mechanism aligns well with our experimental observations and provides an explanation from the perspective of the frequency domain. This research contributes to the understanding of self-

Q

-switching theory and its excitation.

利用干涉仪实现自 Q 开关

自 Q 开关有助于在不采用传统 Q 开关技术的情况下产生脉冲激光器，但该领域的研究和理论发展还很有限。本文介绍了一种基于干涉的自 Q 开关现象，并进行了全面的数值分析。与传统 Q 开关相比，我们的研究结果揭示了自 Q 开关的独特性质，强调了干涉仪的作用。通过结合实验测量和波导模拟，我们提出了一种基于抖动诱导滤波的自 Q 开关机制。这一机制与我们的实验观测结果非常吻合，并从频域的角度提供了解释。这项研究有助于理解自Q开关理论及其激励。
