A method is proposed for the nonlinear conversion of a cw pump beam into a periodic train of intense, short pulses in a stimulated-Brillouin-scattering fiber laser. The pulses that are produced acquire the pump energy stored over a period of the resonator and have a length an order of magnitude shorter than the relaxation time of a hypersonic wave.
