Abstract:
Nonresonant interaction of nonpolar molecules with femtosecond laser pulse is considered using the time-dependent perturbation theory. The solution for the density matrix is obtained in the fourth order of the perturbation; and a general expression for the field energy loss is found. The rigid rotor model is used to numerically calculate absorption by molecular nitrogen.
Keywords:
