The results demonstrate that both materials have potential for amplifying pulses up to the milijoule level for wavelengths around 1048¨C1049 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. %K laser amplifiers %K simulation %K ytterbium lasers %K diode-pumped lasers %K neodymium lasers %U http://www.mdpi.com/2076-3417/3/1/288
