摘要

通过在电调制信号中加入时间和序列调制功能，我们采用 808 nm 和 885 nm 泵浦源对紧凑型 Nd:YAG/Cr4+:YAG 被动 Q 开关激光器进行分时泵浦。通过调整两个泵浦源的泵浦峰值功率和脉冲宽度，实现了各种猝发模式激光器。脉冲链序列之间的重复频率和时间间隔，以及序列内子脉冲之间的时间间隔均可调整，从而解决了猝发模式激光器中精确定时控制的难题。与猝发模式激光器的传统单脉冲输出模式相比，分时抽运 Q 开关激光器显示出明显更好的可控脉冲特性。总之，这项工作有效地拓展了猝发模式激光器的应用范围，为该领域做出了新的贡献。

Burst-Mode Nd: YAG/Cr⁴⁺:YAG Laser With Tunable Pulse Chain Sequence and Intervals

We employed 808 nm and 885 nm pumping sources for time-shared pumping of the compact Nd:YAG/Cr4+:YAG passively Q-switched laser by incorporating time and sequence modulation functions into the electrical modulation signals. Through adjusting the pumping peak powers and pulse widths of the two pump sources, various burst-mode lasers were realized. The repetition frequency and time intervals between pulse chain sequences, as well as the intervals between sub-pulses within a sequence, could be adjustable, addressing the challenge of precise timing control in burst-mode lasers. The time-shared pumping Q-switched laser displayed significantly better controllable pulse characteristic compared to the conventional single-pulse output mode of burst-mode lasers. In conclusion, this work has effectively expanded the application scope of burst-mode lasers, representing a novel contribution to the field.

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.
