Time-dependent dynamics of the H2+ molecule in a strong laser field

Greg Ver Steeg and Klaus Bartschat


This page was created as part of a Research Experience for Undergraduates (REU) project. This project is being undertaken in the Department of Physics and Astronomy at Drake University. It is directed by Professor K. Bartschat and funded by the National Science Foundation under grant PHY-0088917.

The goal of this project is to visualization the effect of a strong short laser pulse on a molecular hydrogen ion. Here is the PDF file of a talk given at an undergraduate symposium at the 2002 meeting of the Division of Laser Science of the American Physical Society and the Optical Society of America.

We have also created several movies that illustrate the combined motion of the nuclei and the electron in a simplified 1D-model with two degrees of freedom, as well a the nuclear and electronic motion separately. Follow these links to see what happens for a wavelength of 800 nm:

Laser intensity 1.0 x 1014 W/m2:
nuclear + electronic motion
nuclear motion alone
electronic motion alone

Laser intensity 1.5 x 1014 W/m2:
nuclear + electronic motion
nuclear motion alone
electronic motion alone

Laser intensity 2.0 x 1014 W/m2:
nuclear + electronic motion
nuclear motion alone
electronic motion alone
