Abstract
The present disclosure relates to systems and methods for reducing thermal effects in double-clad clad optical fiber amplifying systems via control of the pump absorption. One optical fiber amplifying system for reducing thermal effects includes one or more first optical pump sources, each configured to output radiation of a pump wavelength, a bridge optical fiber, having an input configured to receive the radiation of the pump wavelength output by the one or more first optical pump sources and an output, and an active optical fiber that has a first end substantially directly coupled to the output of the bridge optical fiber and a second end. The active optical fiber is configured to amplify radiation of the first active wavelength when pumped with radiation of the pump wavelength.
