a Final population on the state B(v = 0) and X(v = 0) as a function of the central laser frequency. b Contour plot of the final population verse laser intensity and frequency. The three-photon and five-photon resonant frequencies shift with the applied laser peak intensity is indicated by the corresponding linear fittings (black dash-dotted and red dashed curves). c The dependence of B(v = 0) population on the initial injection phase ϕ at the central wavelength of 900 nm. d Dependence of B(v = 0) and X(v = 0) populations on the moments of ionization injection by fixing the carrier phase in the near-resonant case at the central wavelength of 900 nm.
