Y.-J. Rao capability of the short pulse fiber lasers has recently gathered much attention for its potential application in WDM systems. Mollenauer . have demonstrated a tunable soliton laser utilizing a Fabry-Perot filter and a frequency shifter . This method is based on the continuous frequency shifting

Optical fiber lasers,300 μm core diameter fiber doped with neodymium as the laser active gain medium. Since the development of this laser a range of fiber lasers has been constructed using either rare earth ions or optical nonlinearities as the optical gain medium. Although efficient laser action has been observ
