Abstract :
We propose and experimentally verify a new dynamic gain and tilt transient control technique for a multiwavelength forward-pumped Raman fiber amplifier. Using this technique, we demonstrate up to 7-dB static power excursion correction (to within 0.4 dB) and dynamic gain control with submicrosecond response.
