Steering the population transfer of a five-level polar diatomic NaK molecule with two ultrashort transform-limited laser pulses is theoretically investigated using the time-dependent wave packet method. The dynamic Stark shifts resulted from the interaction of polar molecule with laser pulses can be utilized to modulate the transition frequency and transfer efficiently population. The influence of neighboring electronic states on the population transfer is taken into account. By choosing suitable laser pulse parameters, a complete population transfer can be realized. The concept of light-induced potential (LIP) is used to describe the population transfer dynamic process.
