Abstract

We demonstrate an all-fiber monolithic laser source from a gain-managed nonlinear (GMN) fiber amplifier with a CFBG-based pre-compressor that generates high-contrast pulses with a repetition rate of 80 MHz, average power of 1.6 W, and pulse duration of sub-50 fs. The compressed pulse quality can be optimized by tuning the parameters of the seed pulses injected into the GMN amplifier by controlling the pump power of the fiber pre-amplifier. This compact and cost-effective laser system is a simplified design of the GMN amplification-based femtosecond fiber laser systems. With alignment-free characteristics in the amplifiers and clean compressed pulses, it is easy to assemble and use in applications such as multi-photon microscopy.

利用基于 CFBG 的预压缩器从全光纤单片增益管理非线性放大器生成 50 fs 以下脉冲

我们展示了一种全光纤单片激光源，它由增益管理非线性（GMN）光纤放大器和基于 CFBG 的前置压缩器组成，可产生重复频率为 80 MHz、平均功率为 1.6 W、脉冲持续时间为亚 50 fs 的高对比度脉冲。通过控制光纤前置放大器的泵浦功率来调整注入 GMN 放大器的种子脉冲参数，从而优化压缩脉冲的质量。这种激光系统结构紧凑、成本效益高，是基于 GMN 放大的飞秒光纤激光系统的简化设计。该系统具有放大器无需对准的特性和干净的压缩脉冲，因此易于组装并可用于多光子显微镜等应用。

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.
