摘要

马梅雪夫振荡器和增益管理非线性（GMN）放大器能够产生 50 fs 以下的高功率脉冲，但它们之间的密切关系尚未得到系统研究。在本文中，我们用数值方法研究了增益管理非线性对马梅雪夫振荡器的激光演化和输出特性的影响。我们研究了增益光纤长度以及光谱滤波器的中心波长和带宽对激光器中 GMN 演变的影响。结果表明，优化这些腔参数可导致 GMN 演化，从而将马梅雪夫振荡器的输出峰值功率提高 1.5-4 倍。

Investigation on gain-managed nonlinearity in Mamyshev oscillators

Mamyshev oscillators and gain-managed nonlinear (GMN) amplifiers have the capability to generate high-power sub-50 fs pulses, but their close relationship has not been systematically investigated. In this paper, we numerically study the influence of gain-managed nonlinearity on the laser evolution and output characteristics of the Mamyshev oscillator. The impact of the gain fibre length, as well as the central wavelength and bandwidth of spectral filters on GMN evolution in the laser are investigated. The results indicate that optimizing these cavity parameters can lead to the GMN evolution, which can improve the output peak power by 1.5–4 times in Mamyshev oscillators.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
