Abstract

The influences of photodarkening in highly doping ytterbium‐doped fibers (YDFs) on the performance of fiber lasers were investigated in this study. The experimental results show that the threshold and the output power of the laser, respectively, increases and decreases over the pumping time, leading to the deterioration for the conversion efficiency of the laser. The deterioration is caused by the photodarkening of the YDF, which gives rise to additional loss for the YDF. This additional loss increases monotonically and irreversibly with the pump time. However, as the pumping time increases, the irreversible deteriorating process may be gradually fulfilled. The time needed for fulfilling this process depends on the length of the YDF and the pump used. © 2006 Wiley Periodicals, Inc.

## Abstract A novel interrogation of fiber Bragg grating (FBG) in a strain sensor, which is based on Er‐doped fiber laser's transient regime, is reported. The applied strain on FBG changes the laser cavity loss, which in turn modifies the laser's transient regime. The strain value can be obtained b

## Abstract Multiple mode instabilities in erbium‐doped fiber laser are undesirable due to the large amplitude noise in the laser. One scheme is proposed to suppress this kind of instabilities by inserting a highly nonlinear photonic crystal fiber in the ring cavity. The results show that the nonli
