A dramatic field-free molecular alignment which could be achieved after exciting molecules with proper trains of strong ultrashort laser pulses was presented. The limited number of pulses allowed for a complete optimization of the related excitation parameters and provided even better and more robust alignment compared to the accumulative squeezing approach. Analysis showed that a linear molecule without a permanent dipole coupled with the external field via induced polarization.
