A 4-pass structure Er:YAG MOPA system at 1645 nm is theoretically and experimentally investigated. In accordance with the theoretical analysis, the 4-pass structure significantly improved the amplification performance. The highest gain is about 4 with 1 mJ incident seed energy. The power fluctuation and beam quality are improved after the amplification.
