Numerical simulation of high-energy, ytterbium-doped amplifier tunability

Abstract

The study of wavelength tunability for the gain media Yb:CaF2 and Yb:YAG in a regenerative amplifier configuration, was performed by using a simulation code previously benchmarked with real data. The results demonstrate that both materials have potential for amplifying pulses up to the milijoule level for wavelengths around 1048-1049 nm. In light of this, we propose and evaluate their performance as gain media in the pre-amplifier of a hybrid chain operating at 1053 nm.
