Theoretical study of above-threshold dissociation on diatomic molecules by using nonresonant intense laser pulses
The above-threshold dissociation of the ground state of a OH molecule under intense nonresonant laser pulses has been studied using the time-dependent Schrodinger equation with discrete variable representation. The applied field is assumed as a two-color mixed nonresonant laser pulses which has the nonresonant frequency omega and the overtone 2 omega. After modulating the relative phase factor between the omega and 2 omega pulse, we extracted a three-photon absorption peak or a five-photon absorption peak in the ATD spectrum.
