摘要：

In　this　paper　a　Xenon-lamp-pumped　four　rods　pulsed　Nd:YAG　laser　is　presented.　The　influence　of　offset　angle　of　Nd:YAG　rods　and　thermal　stable　regions　in　the　resonator　have　been　analyzed　theoretically,　and　tolerance　of　offset　angle　and　is　given.　A　plane-plane　symmetrical　resonator　has　been　used　in　the　experiment,　and　the　distance　between　two　neighbor　rods　is　two　times　of　that　between　the　mirrors　and　rods.　While　input　electric　power　is　58　kW　and　the　duty　cycle　is　17%,　an　output　laser　with　an　average　power　of　2026　W,　a　peak　power　of　11.9　kW,　maximum　single　pulse　energy　of　60　J　and　a　beam　parameters　product　of　24.5　mm×mrad　has　been　obtained.　The　electro-optical　conversion　efficiency　is　3.49　%,　and　instability　of　the　laser　is　less　than　2　%.　©　2011　SPIE-OSA-IEEE.
