拉曼光纤激光器 输出光束 折射率光纤
2023/4/17
在二极管泵浦的拉曼光纤激光器的多模渐变折射率光纤中,通过飞秒脉冲刻写FBG,可产生接近衍射极限的输出光束。这一技术已经应用于工业(通信、生物医学、材料加工、基础设施和能源行业)中的各种激光和传感器系统。从超长光纤自然瑞利散射引起的随机拉曼激光的发现出发,主讲人将介绍使用fs脉冲刻写具有规则/随机的3D折射率结构的多模、多芯光纤的技术,以及新型光纤所具有的独特激光和传感性能,这种新型光纤有望在物理上...
Analysis of Double Rayleigh Scattering Noise in Higher-order Pumped Distributed Raman Amplifiers
Double Rayleigh Scattering Noise Higher-order Pumped Distributed Raman Amplifiers
2015/8/4
A theoretical analysis of double Rayleigh scattering (DRS) noise in higher-order Raman pumping schemes is presented. Simulations confirm an unexpected DRS noise decrease for pumping schemes above 3 rd...
