摘要

本研究探讨了全固态自调制猝脉冲激光器的理论和实验特性。研究介绍了采用法布里-佩罗特(F-P)结构的激光器的时频和频谱分析,以及相应理论模型的建立。利用增益介质的前后端表面形成 F-P 结构,通过实验构建了自调制猝脉冲激光器,以减少腔内损耗。当激光腔长度为 600 毫米,增益介质长度为 5、6 和 10 毫米时,产生的每个猝脉冲分别包含 56、47 和 28 个子脉冲,猝脉冲宽度相同,均为 2 毫微秒。当增益介质长度为 5 毫米、泵浦功率为 4.5 瓦时,可获得光束质量 M2 = 1.37、平均输出功率为 0.23 瓦的猝发脉冲串。相应的脉冲串重复频率为 0.25 GHz,子脉冲重复频率为 13.66 GHz。激光信号的时频光谱分析很好地呈现了激光光谱信息,即使是目前最高分辨率的光谱仪也无法解析这些信息。

Time–Frequency and Spectrum Analyses of All-Solid-State Self-Mode-Locked Burst Pulse Lasers
The theoretical and experimental characteristics of all-solid-state self-mode-locked burst pulse lasers are investigated in this study. The time–frequency and spectrum analyses of the lasers incorporating Fabry–Pérot (F-P) structures are presented, along with the development of the corresponding theoretical model. Self-mode-locked burst pulse lasers are experimentally constructed to reduce intracavity losses using the front and rear end surfaces of the gain media to form F-P structures. When the laser cavity length is 600 mm and the gain media lengths are 5, 6, and 10 mm, each burst pulse produced contains 56, 47, and 28 subpulses, respectively, with the same burst pulse width of 2 ns. The burst pulse train with beam quality M2 = 1.37 and an average output power of 0.23 W is obtained when the gain medium length is 5 mm and the pump power is 4.5 W. The corresponding burst pulse repetition frequency is 0.25 GHz and the subpulse repetition frequency is 13.66 GHz. The time–frequency spectral analyses of the laser signals provide a good representation of laser spectral information that even the currently available highest-resolution spectrometers cannot resolve.

期刊介绍: Photonics (ISSN 2304-6732) aims at a fast turn around time for peer-reviewing manuscripts and producing accepted articles. The online-only and open access nature of the journal will allow for a speedy and wide circulation of your research as well as review articles. We aim at establishing Photonics as a leading venue for publishing high impact fundamental research but also applications of optics and photonics. The journal particularly welcomes both theoretical (simulation) and experimental research. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material.
