Abstract

After considering the facet residual reflectivity of the semiconductor optical amplifier (SOA), a theoretical model of harmonic mode-locked fiber ring laser based on two SOAs has been established. Using this model, the shape, peak power and pulse width of the pulse output from the harmonic mode-locked fiber ring laser for the different facet residual reflectivity(R1>R2,R1=R2 and R1<R2) of the SOA, has been investigated.The results show that the facet residual reflectivity of the SOA affects greatly the mode-locked pulse, even if the facet residual reflectivity of the SOA is very small.
