摘要
为了得到一种功率可控的光纤激光脉冲光源,采用窄脉宽低重频脉冲光作为种子源,以掺镱光纤为增益介质,利用嵌入式控制技术和脉冲抽运技术,实现了全光纤脉冲激光的多级放大和信噪比提升。结果表明,此种光源输出稳定、信噪比良好,不仅降低了热效应危害,还增强了抽运能量的提取效率,可以作为一般大功率光学系统的光源使用,具有良好的应用价值,市场前景广阔。
In order to get a controllable fiber laser pulse light sources, multistage amplification of all-fiber pulse laser andimprovement of signal-to-noise ratio （SNR） were realized by using pulse laser of narrow pulse width and low repeat frequency asthe seed, Yb3 ＋ -doped fiber as gain medium, and embedded control technology and pulse pump technology. The results show thatthis kind of light source, with stable output and good SNR, not only reduces the harm of thermal effect but also enhances theextraction efficiency of pump energy. The light source can be used in general high power optical systems with high applicationvalue and wide market prospect.
