The time-dependent Schrdinger equations TDSE of the interaction of two-color laser pulse with Pschl-Teller potential and He+ are solved by using the asymptotic boundary condition and symplectic algorithm. The population of ionization, average distance, high-order harmonic generation HHG and population of transition are calculated. The numerical results show that the conversion efficiency of HHG is enhanced in the two-color laser fields, then the qualitative and quantitative analysis for the enhancement of conversion efficiency of HHG are given.
