摘要：

In　this　paper,　the　progress　on　improving　physical　properties　of　functional　materials　by　laser　irradiation　is　reported　and　discussed.　Sintered　with　a　CO2　laser,　a　novel　Ta2O5-based　ceramics　with　maximum　κ　of　450　can　be　obtained　at　ambient　conditions.　The　electrical　conductivity　of　PCDF　induced　by　excimer　laser　irradiation　was　found　to　increase　from　10-13.Ω-1·cm-1　to　10　-4Ω-1·cm-1.　Significant　improvement　in　the　magneto　transport　properties　of　La0.67Ca　0.33MnO3　thin　film　irradiated　by　CO2　laser　in　air　can　be　obtained.　Irradiated　with　a　CO2　laser,　the　polarization　and　piezoelectric　constants　d15　of　Ba0.5Sr　1.5Na0.6K0.4Nb5O15　ceramic　was　found　to　increase　to　120　pC/N.　Based　upon　the　characterization　of　the　samples,　the　phase,　micro-structure,　and　the　mechanism　of　property　modification　in　laser　irradiated　samples　were　analyzed.
