2.9 Erbium Doped Fiber Laser The EDFLs can operate in several wave-length regions‚ ranging from visible to far infrared. The 1.55 region has attracted the most attention because it coincides with the low-loss region of silica fibers used for optical-communications [14]. The erbium absorption line that best matches with available high power pump diodes is in the 980 regime. At this wave-length‚ the absorption cross section of erbium is so low that an excessive amount of fiber would be required for
