A　healing　method　for　fatigue　damage　was　investigated　by　laser　shock　peening　and　laser　irradiation　with　excimer　laser　for　polycrystalline　copper　film.　It　is　found　that　the　sum　of　the　consumed　fatigue　ductility　and　the　total　fatigue　ductility　for　the　damaged　specimen　after　both　laser　treatments　is　equal　to　the　total　fatigue　ductility　for　the　undamaged　specimen　after　both　laser　treatments.　The　evolution　of　the　damage　healing　can　be　replaced　by　that　for　the　undamaged　specimen　after　laser　treatment.　Based　on　the　equivalent　fatigue　damage　evolution,　a　residual　fatigue　life　prediction　method　is　proposed　during　the　damage-healing　process　for　the　copper　specimen.　The　predicted　lives　by　the　proposed　method　agree　well　with　the　experimental　results.
