基于多纵模振荡种子源的高功率窄线宽光纤激光器关键技术分析及研究现状
Key technology analysis and research progress of high-power narrow linewidth fiber laser based on the multi-longitudinal-mode oscillator seed source
摘要
Abstract
Narrow linewidth fiber lasers,based on the multi-longitudinal-mode oscillator seed source,have obvious advantages in engineering applications and space-limited loading platforms.Additionally,they are considered ideal sub-modules for high-power spectral combinations.The time domain of this type of seed is unstable due to the self-pulse effect,causing significant spectral broadening and stimulated Raman scattering effects during the amplification process,which limits their further improvement in output power and affects the purity of laser spectra.In this paper,we introduce four commonly used narrow linewidth seeds.The mechanism and suppression methods of the self-pulse effect in multi-longitudinal mode oscillator seeds are analyzed.Critical technologies essential for the optimization and relevant progress of the multi-longitudinal-mode oscillator seed source and amplifier stages are discussed in detail.A future development outlook is also presented.This paper serves as a useful reference for the design of narrow linewidth fiber lasers based on the multi-longitudinal-mode oscillator seed source.关键词
