Abstract: A packaged fiber laser may include a wound fiber laser spiral including a metal ribbon having ends, surfaces, and edges; a fiber laser on a first one of the surfaces of the metal ribbon; and a metal sheet coupled to a first one of the edges of the metal ribbon or a second one of the surfaces of the metal ribbon. Packaging for a fiber laser may include a cooling plate coupled to a second one of the edges of the metal ribbon or the second surface of the metal ribbon, the cooling plate including: a casing including a cover, a bottom, and an outer sidewall; flow channels formed inside the casing, the flow channels defined by inner sidewalls of the cooling plate, wherein the cover is coupled to a top of the inner sidewalls to enclose the flow channel; and an inlet to deliver coolant to the flow channels.

Abstract: Some embodiments may include a fiber laser, comprising: a variably wound optical fiber, wherein the variably wound optical fiber includes: a first length arranged in a plurality of first loops with a first separation distance between successive ones of the first loops; and a second length arranged in a plurality of second loops with a second separation distance between successive ones of the second loops; wherein the first separation distance between successive ones of the first loops is greater than the second separation distance between successive ones of the second loops; and packaging to remove heat generated by the optical fiber of the fiber laser during operation of the fiber laser, wherein the variably wound optical fiber is fixably mounted to a surface of a heat conductor of the packaging.
