| 1. A system for cooling a fiber amplifier, the system comprising:
a fiber amplifier assembly comprising:
a longitudinally-extending fiber amplifier, the fiber amplifier including a core and a cladding;
a longitudinally-extending jacket having a single substantially centrally-located passage within which the fiber amplifier,
including the core and the cladding, is disposed such that the fiber amplifier assembly defines a passage between the jacket
and the fiber amplifier, including the core and the cladding, for the circulation of coolant therethrough; and
a retaining structure disposed within the passage defined by the fiber amplifier assembly for at least partially maintaining
a spacing between the fiber amplifier and jacket, wherein the retaining structure and coolant comprise an emulsion of phase
change material.
