摘要：

A　high-pulse-energy,　diode-pumped,　solid-state　Nd3+:Y3Al5O12　(Nd:YAG)　two-pass　amplifier　system　without　water　cooler　was　demonstrated　in　this　study.　The　modulation　of　LD　and　Nd:YAG　crystal　rod　and　the　use　of　thermoelectric　cooler(TEC)　in　whole　system　aimed　to　make　the　system　miniaturized.　The　cavity　length　was　280　mm.　And　a　350　mJ　laser　pulse　was　obtained　with　a　pulse　duration　of　9.7　ns,　a　frequency　of　10　Hz　and　a　beam　quality　M2　of　7.7　and　12.3　for　horizontal　and　vertical　directions,　respectively.　A　740　mJ,　10　ns　laser　pulse　for　two-pass　amplification　was　obtained.　©　2018,　Science　Press.　All　right　reserved.
