A　high　energy　high　peak　power　flash-lamp　pumped　pulsed　Nd:YAG　solid-state　laser　is　investigated　in　this　paper.　The　symmetrical　resonator　laser　is　developed　and　rated　at　single　pulse　energy　60J,　peak　power　30KW　with　beam　parameter　product　2mm.mrad.　The　total　system　electro-optics　efficiency　of　the　lamp-pumped　YAG　laser　is　as　high　as　3.1%　with　pulse　width　tunable　between　0.05-2ms.　The　results　are　consistent　with　the　theoretical　analysis　and　simulation.　2009　SPIE.
