Abstract
We have theoretically investigated the molecular alignment by a asymmetric potential created by the superposition of two-color laser fields. The time-dependent Schrodinger equation is solved numerically for different field parameters. We have shown how enhancement or suppression of the molecular alignment can be manipulated by the laser field parameters, such as time between laser pulses, the different intensity of the pulses, etc.
