Abstract

We have generated subpicosecond pulses from a synchronously pumped fiber Raman ring laser with a dispersion compensating delay line. The ring oscillator consists of 100 M of single mode fiber, a grating pair dispersive delay line, and an interference filter as a tuning element.(Fig. 1) The pump source is a CW modelocked Nd*. YAG laser emitting 80 psec pulses at 1064 nm. We observe pulses at the the first Raman stokes band (1100 nm) with pulsewidths as short as 0.8 psec. (Fig. 2)
