We characterized and analyzed the effect of intracavity spectral filtering in Er:fiber laser mode-locked with a semiconductor saturable absorber mirror (SESAM). studied dispersive properties bandpass filters their influence on characteristics generated soliton pulses. Our analysis showed that various sideband structures were induced by filter dispersion profiles shaped through interaction wave. In addition, improved intensity phase noise significantly, we optimal conditions for both types noise. By adding 10 nm to resonator, 2- 2.6 times, respectively.
