A high-efficiency multi-folded Nd:YVO4 slab amplifier is reported. Optimizing the mode overlapping carefully, high extraction efficiency was achieved using the wedged multi-folded configuration with two planar folding mirrors. The amplifier’s performance under different seed powers and different pulse repetition frequencies (PRF) is presented. The 52 W seed at the PRF of 152 kHz was amplified to 101.75 W with the pump power of 92 W, and the corresponding extraction efficiency is 54.3%. And no remarkable deterioration of the beam quality was observed.
