Along　with　laser　technology,　particularly　laser　application　technology　gradually　plays　a　leading　role　in　the　field　of　industrial　field,　high　power　laser　products　and　their　safety　requirements　attracted　more　and　more　attention.　In　fact,　in　laser　welding,　cutting,　surface　treatment　and　other　industrial　applications,　most　concern　was　focused　on　laser　power,　processing　technique.　Laser　beam　quality　and　the　system　of　laser　beam　propagation　and　focusing　are　ignored　greatly.　Furthermore,　the　basic　safety　standards　for　laser　products　had　not　been　widely　publicized　and　strictly　enforced　because　of　the　rapid　development.　This　paper　will　examine　the　underlying　relationship　between　laser　beam　quality　and　laser　manufacturing　and　compare　different　laser　systems.　We　will　show　how　the　laser　safety　standards　could　be　understood　well　and　advocate　for　laser　beam　quality　standard　that　directly　to　mission　requirement.
