AN ALL-FIBER PULSED FIBER LASER MODULE

摘要

An all-fiber pulsed fiber laser module is provided to implement the various switching time by improving the configuration of light attenuator. An optical fiber(13) for the laser oscillation is positioned between the first FBG(Fiber Bragg Grating)(11) and the second FBG(12). The first FBG and the second FBG comprise the resonant cavity. The reflectivity of first FBG is greater than the reflectivity of second FBG. The first pumping source(15) supplies the first pumping light by exciting the optical fiber for the laser oscillation. A variable type light attenuator(14) generates the pulse type laser by inducing the oscillation laser of the periodic Q-switching of the first pumping light.
