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.

Fiber laser having variably wound optical fiber

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.

Fiber laser packaging

Packaging for a fiber laser includes a conduit surrounding the fiber laser and a thermally conductive compound filling a gap between the fiber laser and the conduit setting the fiber laser within the conduit. The fiber laser may have a substantially circular first cross section having a first diameter and the conduit may have a substantially circular second cross section having a second diameter larger than the first diameter of the fiber laser. The conduit may have a splice window cut out from a wall of the conduit and optical potting compound may fix a portion of the fiber laser under the splice window.

A fiber monitoring system for detecting the occurrence of a thermal event, especially of a traumatic nature, in optical fibers while transmitting laser beams includes one or more fiber monitoring apparatuses each having a thermal sensing array supported by a holder board of a laminated dielectric material having a row of clips for retaining optical fibers in alignment with thermal sensor devices of the thermal sensing arrays. The thermal sensing arrays also have electrical circuitry elements for electrically interconnecting the thermal sensing devices in series and enabling electrically connecting the thermal sensing arrays with other circuitry to form a thermal interlock circuit for a laser system.
