The present invention provides a control method and device for an optical amplifier and an optical amplifier. An initial control current offset is obtained according to current input optical power, last input optical power, a maximum working current, a minimum working current, a control current coefficient, and an offset coefficient; a curve of a control current offset changing with time is obtained in combination with adjustment time; and a sum of a control current offset at a current moment and a preset control current is used as a drive current of a pump laser in an optical amplifier according to the curve. |
