La0.67Ba0.33MnO3　thin　films　were　grown　on　LaAlO3　substrate　using　pulsed　laser　deposition.　The　microstructure,　magnetic　and　electrical　properties　of　as-grown,　annealed　and　CO2-laser-irradiated　(CLI)　LBMO　films　were　studied.　It　is　found　that,　after　laser　irradiation,,　the　enhancement　of　the　crystallinity　of　the　film　is　accompanied　by　the　emergence　of　the　plain-like　surface　morphology　with　smaller　roughness.　The　structure　and　magneto-transport　properties　of　LBMO　films　are　markedly　improved　in　several　dozens　of　seconds　via　CO2　laser　irradiation.　Compared　with　the　annealing　treatment,　laser　irradiation　is　a　fast　and　effective　way　to　tailor　CMR　manganites　for　industrial　applications.
