摘要：

After　the　multiwall　carbon　nanotubes　are　irradiated　by　a　1064　nm　wavelength　fiber　laser,　connection　phenomenon　is　found　by　scanning　electron　microscope　(SEM)　observation.　The　SEM　images　clearly　demonstrate　the　melting　and　solidified　phenomenon　between　the　two　overlapping　multi　walled　carbon　nanotubes.　Two　or　more　multi　wall　carbon　nanotube　fuse　together,　and　the　tube　wall　is　smooth　and　complete　without　any　sign　of　damage.　Through　the　transmission　electron　microscopy　(TEM),　the　new　graphite　layers　are　found　in　the　connection.　Besides,　It　is　found　that　in　the　case　of　a　certain　power　density,　as　the　laser　irradiation　time　increases,　the　present　multi-walled　carbon　nanotubes　show　the　trend　of　melting　connecting　to　destruction.
