摘要：

In　this　paper,　the　purpose　of　output　pulsed　laser　with　high-power　and　high　beam　quality　is　discussed,　and　the　structure　of　unsymmetrical　plane-concave　resonator　is　analyzed　theoretically.　We　have　completed　the　laser,　which　could　output　high-power　and　high　beam　quality　with　single　Nd:YAG　rod　pumped　by　double　Xe-lamp　and　unsymmetrical　plane-concave　resonator.　When　the　duty　cycle　was　9%,　the　average　power　of　laser　was　nearly　480　W,　beam　parameters　product　was　better　than　12.7　mm·mrad　and　efficiency　of　electricity　to　light　was　nearly　4%,　which　matched　the　theoretical　analysis　well.　The　laser　could　be　transmitted　by　optic　fiber　of　300　μm　core　diameter　and　its　instability　was　less　than　±　1%.　Processing　experiment　has　proved　that　it　had　good　cutting　quality.
