Abstract
An internally switched fiber laser amplifier is disclosed and claimed. The switch is integrated directly into the fiber amplifier, so that the output power from each fiber amplifier can be switched between N selectable output fibers with minimal (approx. 1%) loss. The switch may be a close coupled pump switch, a spherical mirror or a planar mirror. The fiber laser amplifier may switch both pump and source lights, or may switch only the pump light then combine it with the source light before sending it to a gain amplifier.
