• two-pulse laser
• molecular alignment
• delay time

Field-free alignment of N-2 molecule induced by laser pulse with intensity of 1.5x10(14)W.cm(-2) and duration of 50 fs was investigated by solving time-dependent Schrodinger equation numerically. The results showed that the alignment could be optimized by dividing the laser pulse into two pulses with same duration. The degree of alignment could be maximum with an intensity ratio of 0.3636 at the appropriate delay time of the second pulse relative to the peak of the first pulse.
