Thermal modeling, heat mitigation, and radiative cooling for double-clad fiber amplifiers [PDF]
Journal of the Optical Society of America B, 2018 We report a detailed formalism aimed at thermal modeling and heat mitigation in high-power double-clad fiber amplifiers. Closed-form analytical formulas are developed that take into account the spatial profile of the amplified signal and pump in the ...
