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.
