Abstract A new optical quantum phenomenon by interference of atomic states is discussed. The possibility of formation of induced transient gratings in a resonant medium is shown in the case when the medium is excited by two laser pulses arriving at experimental sample noncoincident in time but from different direction. The theory of such gratings is presented for detuning of the incident light from resonance. A technique is developed for observing such gratings for the 4A2–2E(Ē) transition of ruby.
