Abstract

A temperature controller is used for a gain fiber of a fiber amplifier. The controller includes a heat transfer structure and one or more temperature sinks, such as cooling plates. The heat transfer structure supports the gain fiber and is disposed in thermal contact with it. Portions of the temperature sink(s) are disposed in different thermal conductivity with sections of the heat transfer structure. For example, the sinks may have different material properties and/or material thicknesses. Also, portions of the temperature sink(s) can have different cooling rates. The different thermal conductivities conduct the heat from parts of the gain fiber differently from one another. In the end, an onset of Stimulated Brillouin Scattering (SBS) on the laser light path can be mitigated by conducting heat from the gain fiber with the different thermal conductivities.
