Which outcome occurs when the erbium concentration is locally depleted within a doped fiber amplifier?

💡 Explanation

Spatial hole burning creates uneven saturation because stimulated emission depletes the population inversion locally, therefore gain clamping becomes spatially uneven, rather than clamping equally, because depletion varies per location within the erbium-doped fiber section.
