Hydrogen atoms with principal quantum number $n=10$ have been laser excited to states between n=44 and 67 in the presence of a strong microwave field whose frequency ω was adjustable between 5.9 and 8.0 GHz. The excitation probability has been studied as a function of n, ω, microwave field strength and the number of microwave photons absorbed.
