摘要：

Diode　end-pumped　the　Brewster　cut　Q-switched　Nd:YVO4　master　oscillator　and　power　amplifier　(MOPA)　of　Nd:YAG　laser　with　high　energy,　narrow　pulse　width　output　has　been　developed.　The　single　pulse　energy　of　master　oscillator　is　0.16　mJ　at　5　Hz,　and　the　pulse　width　is　0.964　ns.　In　order　to　avoid　the　ASE　effect　of　the　Nd:YAG　amplifier,　the　isolator　and　the　1.5　degree　cut　Nd:YAG　crystal　are　adopted.　After　Nd:YAG　double　pass　preamplifier,　the　single　pulse　energy　of　88　mJ　and　the　pulse　width　of　0.972　ns　are　achieved.　After　Nd:YAG　single　pass　post　amplifier,　the　single　pulse　energy　of　3.25　J,　pulse　width　of　1.051　ns　and　M2=1.9　are　acquired.　The　unstable　degree　of　laser　output　is　less　than　±3%.
