Performance and stability analysis of multiwavelength fiber laser based on hybrid raman-EDF in clockwise and anti-clockwise propagation / Nor Ain Md Saad

A performance and stability comparison of multiwavelength fiber laser based on Raman-Erbium doped fiber (EDF) in clockwise and anti-clockwise is demonstrated and analysis of the finding is conducted. By tapering a section of erbium doped fiber ends with two-taper successively and the configuration o...
