• Article: Raman-induced noiselike pulses in a highly nonlinear and dispersive all-fiber ring laser.

  ABSTRACT: Dual-wavelength noiselike pulses are generated in a fiber ring laser. A first series of pulses is induced at a wavelength of 1550 nm by the interplay of an erbium-doped fiber and nonlinear polarization rotation. From the Raman gain of these pump pulses emerges a second series of Stokes pulses at 1650 nm. With adequate control of the polarization states in the cavity, the noiselike Stokes pulses extend over 84 nm in the Ultralong-wavelengths band (U-band), while the pump pulses span over 46 nm.

• Article: Broadband self-pulsating fiber laser based on soliton self-frequency shift and regenerative self-phase modulation.

  ABSTRACT: We demonstrate experimentally and numerically the operation of a self-pulsating fiber laser based on the cascaded effects of soliton self-frequency shift and self-phase modulation spectral broadening. The combination of those two effects triggers and sustains the propagation of picosecond pulses in the cavity. At one of the outputs, the laser emits a supercontinuum with spectral width in excess of 150 nm at the repetition rate of 95 kHz.

• Article: Fabrication and characterization of a pulsed fiber ring laser based on As2S3.

  [show abstract] [hide abstract]
  ABSTRACT: We demonstrate the operation of a fiber ring laser using a 19.5 cm segment of As2S3 chalcogenide fiber. The laser is passively mode-locked via nonlinear polarization rotation and provides two different operation regimes of picosecond and noiselike pulses. This ring configuration also enables an accurate measurement of the chromatic dispersion of the chalcogenide fiber.
