|
Abstract:
本文基于MOPA结构搭建了铒镱共掺光纤放大系统，通过对光纤放大器的线宽和光谱特性进行测量与分析，研究了光纤放大器中放大的自发辐射(ASE)对激光器线宽的影响。分析表明，在光纤放大器中，ASE作为噪声会引起激光线宽展宽，且呈现出正相关的特性。
This article constructs an erbium ytterbium co-doped fiber amplification system based on the MOPA structure. By measuring and analyzing the linewidth and spectral characteristics of the fiber amplifier, the influence of amplified spontaneous emission (ASE) in the fiber amplifier on the laser linewidth is studied. Analysis shows that in fiber amplifiers, ASE as noise can cause laser linewidth broadening and exhibit a positively correlated characteristic.
