Thermal effects, which limit the average power, can be minimized by using low-doped, longer gain fibers, whereas presence of nonlinear effects requires use of high-doped, shorter fibers to maximize the peak power. Proposed solution of the problem is the use of varying doping levels along the gain fiber to circumvent to mitigate the trade-off between thermal load and nonlinear effects. © 2013 The Chamber of Turkish Electrical Engineers-Bursa.EnglishFiber lasersThermal loadAverage powerDoping levelsGain fibersHigh power fiber lasersNonlinear effectPeak powerElectronics engineeringConference Paper10.1109/ELECO.2013.6713918
