A laser induced quadrupole-dipole collisional energy transfer system of Ca-Sr is proposed and the four-state quadrupole-dipole laser induced collisional energy transfer model is presented. The excitation spectrum calculated for the Ca-Sr system is characterized by a doublet structure and a width which is about twice wider than the dipole-dipole laser induced collisional energy transfer results. Calculating results show that the full width at half peak of the profile becomes larger and the quasi-static wing tends to be a broad flat as the field intensity increases, which are different from the reported results of dipole-dipole laser induced collisional energy transfer processes, dipole-quadrupole and quadrupole-quadrupole. A cross-section of 2.48× 10^{-14} cm^{2} at a laser field intensity of 5.21× 10^{7} V/m is obtained which indicates that the quadrupole-dipole process can be an effective way to transfer energy selectively.
