Claim:
1. A fiber optic laser comprising: a hollow spool structure housing a fiber in a spiral groove in an interior surface of said hollow spool structure, wherein the fiber is mechanically supported along an entirety of its length within the hollow spool structure; and fluid channels formed within the hollow spool structure, wherein a quantity of coolant is movable through the fluid channels to provide high-precision thermal management of the fiber, wherein said hollow spool structure includes an integral flat surface adapted to carry a passive optical fiber and for routing said passive optical fiber around a spool core and back to the spool core at a proximal end of an active doped fiber, wherein a plane at which the passive optical fiber meets the proximal end is tangential to a plane of the active doped fiber at the proximal end.
