Influence of the orientational equilibrium time on the inversionless light amplification eeffect with selective on the states of oriented molecules

The possibility of switching from opaque via transparent to a strongly amplifying state without a change in the noninverted population of their energy levels is analyzed. Life time of the excited level and equilibration time parity influence for the strengthening factor is numerically considered, on the basis of the connected system of the Boltzmann equations for the ground and excited energy states having different energy of interaction with the dc field.
