Effects of the EDF length and oscillation reflectivity on the output power of a 1.55 pm ring fiber laser system

The effects of varying the Erbium doped fiber (EDF) length and the loop-back reflectivity of an all fiber ring laser system are presented. Two characteristics of the output power, namely the lasing threshold and the maximum power are analyzed. The reflectivity is taken as the percentage of the la...
