The fiber attenuator was combined with a fiber Bragg grating, which was used as the end mirror and the wavelength selector of the laser system. The fiber attenuator was implemented with the excitation of transverse vibration by a modulated acoustic wave. The transverse vibration or micro bending led to the coupling of the core mode and cladding modes. Through this mechanism, the feedback level from the fiber grating or the Q factor of the laser can be well controlled. The Q-switched fiber laser based on this scheme can be quite simple.application/pdf78819 bytesapplication/pdfen-US[SDGs]SDG7Attenuation; Diffraction gratings; Feedback control; Frequency modulation; Mirrors; Q factor measurement; Q switched lasers; Vibrations (mechanical); Acoustically modulated fiber attenuators; Fiber Bragg gratings; Fiber lasersjournal article10.1109/68.8742192-s2.0-0034266796WOS:000089271600003http://ntur.lib.ntu.edu.tw/bitstream/246246/144165/1/02.pdf
