With　the　rapid　development　of　laser　manufacturing　technology,　laser　technology　had　been　widely　applied　in　industry.　The　applications　of　laser　manufacturing　technology　in　the　field　of　automobile,　aerospace,　iron　and　steel　metallurgy　demonstrate　its　advancement　and　universality　in　development　ideas　such　as　low　energy　consumption,　short　flow　process　and　green　environment　protection.　Two　new-type　lasers,　i.e.　high　power　semiconductor　laser　and　fiber　laser　which　represent　future　development　direction　of　laser　manufacturing　systems　are　also　introduced　in　hopes　to　change　the　current　status　of　mainly　relying　on　import　of　laser　manufacturing　equipment　for　use　in　large　industry,　and　to　form　a　new-generation　laser　manufacturing　industry　chain.
