Shortening pulses from subnanosecond to picosecond by means of ultrafast temporal filtering in an optical fiber.
Taking advantage of the combination of stimulated Raman scattering and nonlinear polarization rotation in a single-mode optical fiber, a temporal reshaping of subnanosecond pulses is achieved by means of both spectral and polarization filtering. Shortening of 650 ps down to 43 ps temporally and spectrally stable pulses is experimentally obtained. Numerical simulations supporting this new temporal filtering are presented.
