摘要: Interaction of femto-second pulsed laser with a nitrogen molecule at various angles is investigated numerically in the present study We propose a three-dimensional time-dependent Schrodinger equation (TDSE) solver using finite volume method (FVM) with single-active-electron (SAE) assumption We construct the model potential by combining the soft-Coulomb potential and Yukawa potential and fitting both the first ionization energy and orbital type of highest-occupied molecular orbital (HOMO) of a N(2) molecule The ratio of simulated maximum (chi = 0 degrees) to minimum (chi = 90 degrees) Ionization yield is 1 9 and it agrees more favorably with the converted experimental data (2 3-3 3) than the MO-ADK model does (10 0) This shows that the proposed model potential in the 3D TDSE solver can faithfully predict the ionization of a nitrogen molecule under strong pulsed laser incidence and is a very useful tool for future application in similar analysis of more complicated molecules (C) 2010 Elsevier BV All rights reserved
