Abstract

Low noise laser sources with narrow linewidth and low intensity noise are key tools in a broad range of applications such as optical sense, microwave photonics, coherent optical communications and so on. The report gives an introduction about our research progress of the narrow-linewidth single frequency DFB fiber lasers. An internally developed DFB fiber laser is developed. The noise characteristic of laser output is studied in detail. The frequency noise in low Fourier frequency is reduced via using the low noise pump and intracavity optical negative feedback. Furthermore, an injecting lock scheme is used to reduce the intensity noise. A fiber laser output with low frequency noise and low intensity noise has been demonstrated.
