| Abstract: | From the basic interaction of the system we have obtained the equation of motion of two laser-cooled ions in a Paul trap. Using numerical method we studied the dynamic behaviors of the system and found that its final states were determined sensitively by parameters and initial conditions and there existed multi-attrators, frequency-locking and transient chaotic states. |

| Keywords: | Paul trap laser cooling chaos attractor frequency-looking. |
