With　the　development　of　laser　technology,　laser　application　technology　increasingly　plays　a　leading　role　in　the　field　of　industry.　High　power　laser　products　and　their　safety　requirements　are　attracting　more　attention.　In　laser　industrial　applications,　laser　beam　quality　and　the　system　of　laser　beam　propagation　and　focusing　are　greatly　ignored.　Furthermore,　the　basic　safety　standards　for　laser　products　have　been　neither　widely　publicized　nor　strictly　enforced　because　of　rapid　development.　This　paper　examines　the　underlying　relationship　between　laser　beam　quality　and　laser　manufacturing,　and　makes　a　comparison　among　different　laser　systems.　It　is　also　shown　how　the　laser　safety　standards　could　be　better　understood　and　laser　beam　quality　standard　is　advocated　that　directly　relates　to　a　mission　requirement.　©　2011　Higher　Education　Press　and　Springer-Verlag　Berlin　Heidelberg.
