The model not only provides a fast means of modeling transients in gain-clamped EDFA′s, but also shows clearly how the laser relaxation oscillation frequency, damping constant, and oscillation amplitude are affected by design parameters through explicit analytical expressions. Modeling shows quantitative agreement with experiments when the spectral-hole burning effect plays minor role on EDFA transients.
