Paper Abstract
The effect of self-induced transparency (SIT) for probe field in the N-type atoms is predicted. The two ground states of
atoms are coupled via two photon Raman transitions by means of probe and driving fields, which are strongly detuned
from one photon resonance, while the probe field is also resonantly connected to third optical transition from the second
ground state. It is found that the probe absorption features the Doppler profile in dependence on Raman detuning δ with a
narrow deep for small values of δ. However, in the vicinity of δ=0, an ultra-narrow EIT resonance with subnatural width
is observed caused by the probe field itself. The effect is explored analytically and numerically. A scheme is elaborated
to demonstrate the SIT experimentally in the alkali vapors at room temperatures.
