主　　题：laser-induced collisional energy transfer(LICET) tuning range cross section strong field effect. 

摘      要：Theoretically based on the four-level model,one LICET process in Eu-Sr system in both weak and strong fields was calculated by immediate numerical *** results in weak field are in fair to good agreement with analytical *** results in strong field show that:(a)the peak of the LICET profiles moves to the violet side and the tuning range of the profiles obviously becomes narrower when the laser field intensity increases;and(b)numerical results in strong field differ a lot from analytical ones,which indicates that in strong field,the analytical expressions are not applicable any longer.
