Abstract: Dynamics of creation and distraction of coherent states resonantly excited by pair of laser pulses following each other with temporal delay in germanium crystal doped with shallow impurities has been theoretically considered. The power of excited radiation, lattice tempera-ture and limit permissible of inhomogeneous line broadening that necessary to observe of Ramsey interference in such system have been estimated.

Keywords: germanium, shallow donors, laser excitation, coherent states, Ramsey interference.
