Opis:: A strong laser field ( ≈ 10¹⁵ W/cm²) induced low-collisional-energy charge transfer process in Ne⁺-He system is explored. In the low collisional energy regime, the cross-section can be ≈ 10¯¹⁷ cm² which is about two orders of magnitude higher than the collision-only process. With increasing collisional energy the cross-section curve displays flattens and the charge capture tends to be practically independent of the laser detuning. In addition, we find that the capture probability in this Ne⁺-He system varies significantly with the laser polarization angle.

Opis:: 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 $2.48 \times 10^{-14} cm^{2}$ at a laser field intensity of $5.21 \times 10^{7}$ V/m is obtained which indicates that the quadrupole-dipole process can be an effective way to transfer energy selectively.
