Temperature Dependency of Ytterbium-Doped Fiber Laser (YDFL) Based on Fabry-Perot Design Operating at 915 nm and 970 nm High Power Pumping Configuration

Fady I. El-Nahal, Abdel Hakeim M. Husein


The variation of the output power of Ytterbium-doped fiber lasers (YDFLs) with temperature has been evaluated. Temperature-dependent rate equations of ytterbium fiber laser based on Fabry-Perot design have been discussed. The results demonstrate that the output power decrease with the increase of temperature. The effect of the temperature on the output performance increases by increasing the pump power. The effect of temperature can be ignored only for lower pump power. The theoretical result is in agreement with the published experimental results.
