This　letter　describes　the　increase　in　electrical　conductivity　of　poly(vinylidene　fluoride)　induced　by　excimer　laser　irradiation　with　lambda=248　nm.　The　electrical　conductivity　was　found　to　increase　from　10(-13)　to　10(-4)　Omega(-1)　cm(-1).　As　a　result,　experiments　produced　a　transition　in　the　property　of　the　material　from　an　insulator　to　a　conductor.　Optimal　conditions　for　laser　irradiation　were　determined　in　terms　of　the　laser　energy　density,　the　repetition　frequency,　and　the　total　number　of　laser　shots.　This　letter　also　discusses　the　micromechanics　of　increasing　conductivity　in　the　light　of　Raman　spectroscopy　and　x-ray　photoelectron　spectroscopy.　(c)　2006　American　Institute　of　Physics.
