摘要：

A　home　made　high-power　laser　processing　system　for　industry　application　is　reported.　The　symmetrical　parallel　plane　four-rod　series　resonator　CW　Nd:YAG　laser　with　krypton　lamp-pumped　has　been　developed,　the　output　power　is　more　than　2100　W　with　beam　parameter　product　of　24　mmmrad.　The　total　electro-optics　efficiency　of　system　with　lamp　pumped　YAG　crystal　is　as　high　as　3.5%.　The　output　laser　is　transmission　with　600　μm　core　diameter　fiber.　The　key　factors,　such　as　high-power　laser　output,　high　efficiency　fiber　coupling　and　controlling　system　of　adaptive　processing　at　the　premise　that　the　high-power　laser　processing　system　guarantees　the　beam　quality,　are　analyzed.　It　is　conclusion　that　the　laser　processing　machine　is　a　stability,　fastness,　operating　convenience　system.　The　system　can　connect　with　moving　components,　such　as　robot　and　machine,　and　meet　the　processing　requirements　of　industry　application.
