Abstract：

A　compact　high-energy　solid-state　Nd:YAG　master-oscillator　power　amplification　system　side-pumped　by　laser　diode　is　presented.　We　use　the　thermoelectric　cooler　in　the　whole　system,　and　a　compact　and　miniaturized　laser　system　is　achieved.　A　Nd:YAG　crystal　rod　with　diameter　of　7　mm,　length　of　100　mm　and　doping　concentration　(atomic　number　fraction)　of　1.1%　is　used　in　the　master　oscillator.　We　obtain　a　laser　pulse　with　maximum　pulse　energy　of　350　mJ,　pulse　width　of　9.7　ns　under　repetition　rate　of　10　Hz.　A　Nd:YAG　crystal　rod　with　diameter　of　7.5　mm,　length　of　134　mm　and　doping　concentration　of　1.1%　is　used　as　gain　medium　in　power　amplification　stage.　Finally,　we　obtain　the　laser　pulse　with　energy　of　700　mJ　and　pulse　width　of　10　ns.　©　2018,　Chinese　Lasers　Press.　All　right　reserved.
