Abstract

We develop a new model to simulate and analyze sidelobes' influence on the pulses characteristics and performance of fiber Bragg grating-based Q-switched fiber laser. Our simulation results show that uniform fiber Bragg gratings with sidelobes negatively affect the Q-switched fiber laser performance. Their sidelobes introduce undesired multi-peaks and decrease the output pulses energy, while the apodized fiber Bragg grating with high sidelobe-suppression-ratio is able to eliminate the multi-peaks effectively and generate higher energy pulses with smoother profile. Experimental work has been conducted to validate the proposed model and verify the simulation results.
