Narrow Linewidth Fiber Laser for Fiber Sensing
摘要
As a representative of modern laser technology, fiber laser has become a research hotspot in recent years and has a wide market prospect. Single-longitudinal-mode narrow linewidth fiber laser is an important branch of fiber laser technology with many advantages, such as narrow line width, long coherence length, easy to realize high power, strong system stability and miniaturization. Therefore, it is widely used in dense wavelength division multiplexing system, optical fiber sensing system, remote measurement and control radar, remote communication system and other application fields, and plays a very important role.
