I am working on a research project involving the closed orbits of hydrogen in the presence of an external electric field and I am curious what a reasonable approximation for the electric field strength would be. I know that there are vast differences in particle accelerators but I have some information on other parts of the experiment set up that may help give a better approximation.
$1.$ The laser used to excite atoms to a higher energy state is a YAG laser producing light at $532nm$ that is then shifted to $698nm$ through an optics system.
$2.$ The molecular hydrogen beam $H_2$ operates at $4keV$.
Thanks for any information you can give.
