摘要：

High-power　all-solid-state　sub-nanosecond　lasers　have　the　advantages　of　small　size,　low　cost,　narrow　line　width　and　high　peak　power.　They　have　important　application　value　in　many　fields.　In　order　to　obtain　high-power　sub-nanosecond　laser　output,　a　sub-nanosecond　seed　laser　was　first　obtained　through　a　passive　Q-switched　laser,　and　then　an　LD　side　pump　module　was　used　to　design　a　dual-module　dual-pass　amplification　experiment.　At　a　repetition　rate　of　1　kHz,　a　laser　output　with　an　average　power　of　10　W,　a　pulse　width　of　816　ps,　a　line　width　of　39　pm,　and　a　beam　quality　M2of　less　than　1.8　was　obtained.　The　overall　magnification　the　amplifier　was　over　95　times.　©　2020,　Editorial　Board　of　Journal　of　Infrared　and　Laser　Engineering.　All　right　reserved.
