摘要

We propose a new method to separate different orders of an all-fiber passive Q-switching stimulated Brillouin scattering (SBS) laser.We use two fiber Bragg gratings connected by two circulators for the filtering.We obtain a stabilized pulse laser and measure the pulse width of different orders.The first order of SBS has a central wavelength of 1549.75nm,an average output power of 9mW,and a pulse width of 400ns.The pulse width of SBS is reduced by the higher-order signals with the larger fluctuations.
