Popis:	We study and compare the performance of Yb:CaAlGdO 4 - and Yb:CaF 2 -based regenerative amplifiers at low (5 to 10 kHz) and high (up to 500 kHz) repetition rates. Both materials allow for pulse energies of Thanks to the good thermal properties of Yb:CaF 2 and Yb:CALGO, the extracted energy has the potential to be significantly increased with further pump power scaling. Shorter pulses are also potentially achievable by optimizing the design of stretcher and compressor in order to better compensate higher-order dispersion and reduce nonlinear effects. These laser sources are extremely interesting for industrial applications where high pulse energies at relative high repetition rates allow to considerably reduce the manufacturing throughput time.
