Parametric soliton laser.
The parametric soliton laser is described. It operates through parametric four-photon mixing in a synchronously pumped ring cavity. A dispersion-shifted single-mode fiber at 1.525 microm is used, and the pump wavelength is set at the wavelength of zero chromatic dispersion. Clear evidence of a threshold was found, and a pulse width of 210 fsec was obtained. An intensity-dependent carrier frequency was observed and is explained by phase matching through the nonlinear index.
