Abstract
We study the dynamics of gain of fiber amplifiers and fiber lasers. We present a model — the quasiband model — that allows for derivation of an analytical expression for the gain coefficient of an optically pumped doped glass fiber. We concentrate the discussion mainly on the erbium-doped fiber amplifier. We will however discuss other fiber amplifiers and fiber lasers too.
