Abstract

Using two 20 mm in diameter, 1.4 mm thick, 5 at% doping Yb:YAG ceramic active elements (AEs) we reached 233 mJ at 143 Hz in the output with 70 ns, 30 mJ input pulses. According to our 3D calculations we extracted about half of the stored energy. To our knowledge, this output result is the best among all high repetition rate cryogenic pulse Yb:YAG ceramic thin disk laser systems.
