  • Abstract
    We demonstrate a novel approach to increase the Q-switching repetition rate of the fiber ring laser. This Q-switched fiber laser integrates an apodized fiber-Bragg-grating (FBG) reflector and a Fabry-Perot (FP) etalon constructed from cascaded chirped FBGs into the cavity. The apodized FBG reflector acts as wavelength discriminative component for oscillation, while the FP etalon is tuned periodically using the piezoelectric transducer (PZT) and functions as a Q-switching component. By adjusting the tuning range of the FP etalon, we obtain 3.5-, 7-, and 14-kHz Q-switched pulses train with constant PZT modulation frequency of 3.5 kHz.
