Theoretical analysis of doping management and its effects on power scaling

Abstract

Thermal load and nonlinear effects are two contrary phenomena that make up important drawbacks in rapid progress of high-powerber lasers. To minimize the thermal load, which limits the average power, doping concentration should be decreased, which brings about increasing length of theber. In contrast, the presence of nonlinear effects and their management demand the use of high-doped, shorterbers in order to maximize the peak power. Management on doping of gainber and obtaining a specic doping prole function along the short gainber is a proposed solution for prevention of the exchange between thermal load and nonlinear effects. The study shows two different approaches for keeping the temperature levels down in addition to obtaining power scaling proles.
