## Abstract An actively modeβlocked fiber laser (AMLFL) based on the hybrid gain of a dispersionβshifted fiber (as the Raman gain medium) and an Erbiumβdoped fiber (EDF) is introduced. The fiber Raman gain mechanism can effectively suppress the gain competition of an EDF, which usually results into

We show what we believe is the first demonstration of an ytterbium-doped strictly all-fiber active mode-locking laser. The active control of the laser is based on in-fiber amplitude modulation at 11 MHz, which is achieved by using an all-fiber acoustooptic superlattice modulator driven by standing a
A passively mode-locked fiber ring laser is demonstrated using a 49 cm long bismuth oxide based erbium-doped fiber (Bi-EDF) and a fast semiconductor saturable absorber. Stable and clean short pulses are achieved because of these short and high nonlinear characteristics of the Bi-EDF. The laser opera
Supercontinuum generation with considerable flatness and low fluctuation is investigated in nonlinear fibers by amplification of pulsed seed signal of a stable mode locked bismuth oxide based erbium doped fiber laser. Spectral expansion from 980 to 1750 nm is obtained by 340 fs pulses at 1560 nm amp
Although the harmonics are suppressed at 15 GHz, the RL is still present. This resonance can cause radiation at 15 GHz from the circuit. At 7.5 GHz the passband selectivity is destroyed with a maximum RL value of 17.5 dB. Therefore, with the inclusion of U-PBGS, the match at fundamental frequency ha
