“…According to our previous work [19], when the signal is applied on the PZT, the PS will be induced into the CFBG and the peak will appear on the transmission spectrum. With the increase of the magnitude of PS, the center wavelength of the peak moves toward the long wavelength region.…”

“…In this paper, the PZT is used to induce phase shift (PS) in CFBG, and the PZT-based PS-CFBG has been successfully applied in SLM FRL [17,18]. For further study, the PZT-based PS-CFBG has been theoretical and experimental analyzed in our previous work [19]. It turns out that the PZT-based PS-CFBG has extremely narrow transmission peak and sharp band-pass spectrum.…”

In this letter, a Q-switched erbium-doped fiber ring laser (EDFRL) with piezoelectric transducer (PZT)-based phase shift chirped fiber Bragg grating (PS-CFBG) has been proposed and demonstrated first. As known, the phase shift can be induced and wiped periodically by applying a modulation signal on the PZT. This makes it possible for the PZT-based PS-CFBG to be used in Q-switched EDFRL. To verify the performance of this Q-switched EDFRL system, some theoretical analyses and experiments have been performed. It is found that, when the PZT is modulated by a signal with frequencies of 1 and 2 kHz, pulse widths of the Q-switched pulse train are 19.8 μs and 15.6 μs, respectively. Besides, the corresponding pulse energies are 1.16 μJ (1 kHz) and 1.91 μJ (2 kHz) with a pump power of 90 mW.
