Compared with other light sources, fiber laser pointer have many advantages when used as sensing light sources. First of all, fiber lasers have excellent performance such as high utilization rate, tunable, good stability, compact size, light weight, convenient maintenance and good beam quality. Secondly, the fiber laser can be well coupled with the fiber, and is fully compatible with the existing fiber devices, and can perform all-fiber testing.
Now, fiber-optic sensing based on tunable narrow line-width fiber lasers is one of the popular applications in this field. The fiber laser has a very narrow spectral line width, an ultra-long stem length, and fast modulation of the frequency. Applying this narrow linewidth fiber laser to a diffuse sensing system can achieve ultra-long interval and ultra-high-precision fiber sensing. In the United States and Europe, this kind of sensing technology based on tunable narrow line-width fiber lasers is widely used. It is estimated that the demand for such example fiber lasers is also over 100 per year.
Application of fiber laser in communication. Compared with other types of lasers, fiber optic green laser pointers have obvious advantages in terms of compact layout, heat dissipation, beam quality, volume, and compatibility with existing systems, and are widely used in the field of communications.
