Abstract: To study the possibility of amplifying the radiation of femtosecond fibre lasers in thin-rod active elements, amplifying modules based on thin rods made of broadband Yb : CaF2 and Yb : Y2O3 materials are developed. It is shown that the gain in Yb : YAG and Yb : Y2O3 elements is limited because only part of the broadband signal is amplified, while amplification in Yb : CaF2 elements occurs in a wider spectral range but is weak due to a small emission cross section. Amplification from submicrojuole to submillijoule level in the regenerative amplification regime is demonstrated. The new broadband Yb : CaF2 and Yb : Y2O3 materials can amplify radiation with a considerably broader spectrum than Yb : YAG.

Keywords: femtosecond laser pulses, thin-rod active elements, ytterbium-doped laser materials, spectral narrowing.
