Over 250 J pulse energy with around 30 ns pulse duration at 0.2 Hz repetition rate was demonstrated by laser diode pumped cryogenically cooled Yb:YAG ceramics laser. In this report, experimental results of wavefront deformation and energy amplification on 10 Hz repetition rate condition will be presented.
