The　formation　of　copper　excited　state　4d＇　4F9/2　and　its　transition　in　the　copper　plasma　induced　by　laser　are　studied　by　the　time-resolved　spectra　technology.　The　experimental　results　indicate　that　the　formation　of　excited　state　4d＇　4F9/2　follows　different　mechanisms,　such　as　recombination　of　electrons　and　ions,　collision　between　the　elemental　species　and　self-absorption　of　atomic　lines,　during　the　evolution　of　plasma.　When　the　collision　between　particles　is　severe,　the　excited　state　4d＇　4F9/2　transits　to　low　energy　states　4p＇　4D7/2o　and　4p＇　4F9/2o　with　the　same　probability.　After　500　ns　of　plasma　radiation,　the　collision　becomes　weak,　and　the　excited　state　4d＇　4F9/2　mainly　transits　to　4p＇　4D7/2o　with　emitting　the　characteristic　line　Cu　I　359.91　nm.
