Abstract
Measurement of the stimulated emission from a cell containing CS2 mole cules irradiated by two laser pulses is discussed. Both an approximate adiabatic solution and an exact numerical solution have been used to explain the results. It has been proved that, to obtain maximal signal , the pulses must come to the cell in a counterintuitive order, that i s, the stimulating pulse arrives prior to the pump pulse. The connecti on with the phenomenon of efficient population transfer has been point ed out.
