In recent years, fiber lasers have been focused as research topic in the field of laser. It is widely applicable in the field of modern optical communication, optical sensing, materials technology, life sciences and precision mechanics, national defence science ,etc.
Fiber laser is typical representative of the third generation lasers. Fiber lasers have great ad-vantages compare to any other lasers, such as long lifetime, small size, high efficiency, compact structure, etc.
This report begins by introducing the basic knowledge of lasers. Then the overview the is given on operating principle and research status of fiber laser, some typical fiber lasers. In the end the application and future prospects of fiber lasers are introduced
