A　high　energy　high　peak　power　flash-lamp　pumped　pulsed　Nd:YAG　solid-state　laser　is　reported　in　this　paper.　The　symmetrical　resonator　laser　is　developed　and　rated　at　single　pulse　energy　60　J,　peak　power　30　Kw　with　beam　parameter　product　2　mm·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　∼　2　ms.　The　results　are　consistent　with　the　theoretical　analysis　and　simulation.
