                     ------- |1>
 ```
 
+Such system  can exibit  slow and  fast light behavior  for the  cases when
+field 2 connecting  |2>-|3>|is weak and treated as a  probe field, field 1
+is strong  and field 3 serve  as a switch  toggling slow (field 3  is off),
+fast (field 3 is on and strong) light, and situations in between.
 
+Below the examples of fast and slow propagation for the following set of parameters:
+```
+G3=3.4e7         // decay rate of level |3> in 1/s
+G4=3.8e7         // decay rate of level |4> in 1/s 
+gt=3.1416e+04    // repopulation rate in 1/s
+z=1.5e-2         // cell length in m
+N=1e10*(1e6);    // number of particles per cubic m i.e. density
+delta1=0;        // field 1 one photon detuning 
+delta2=0;        // field 2 --------//---------
+delta3=0;        // field 3 --------//---------
+```
+
+Slow light behavior is observed for the 1 \mu S long Gaussian pulse and
+the following fields parameters
+```
+E1=7.5e7;  // field  1 Rabi frequency  in 1/s
+E2=1;      // field  2 --------//----------- 
+E3=0;      // field  3 --------//-----------
+```
+fields 1 and 3 have no time dependence at the input of the cell.
