Therefore,the linewidth of a Yb3+ doped DFB fibre laser was measured with the delayed self-homodyne detection method in the present work.
DFB单频光纤激光器输出的超窄线宽作为光学系统中的一个重要参数需要进行准确的测定,因此,采用延时零拍法重点对1053 nm波长的DFB掺Yb3+光纤激光器的超窄线宽进行了测量,并且研究了差拍光电流谱线的输出特性。
The theoretical and experimental results show that multimode fiber can also be used in delayed self-homodyning linewidth measurement system.
从理论上对零拍测量法测量激光线宽系统的分辨率进行了计算,并在理论和实验结果中证明多模光纤也可用于光纤延时零拍系统。
