Abstract :
A three-wavelength reconfigurable cascaded Raman laser has been demonstrated in a phospho-silicate fiber using two types of Raman shifts. This laser provides high slope efficiencies compared to germano-silicate fiber lasers and control of the output powers. It enables to reduce (a) Output Stokes powers and total power versus pump power (b) Output spectrum with equalized power at the three output wavelengths.
