(color online) Effect of velocity for the three-level Ξ type system in (a) ¹³³Cs 6²S_1/2 → 6²P_3/2 → 6²D_5/2, (b) ⁸⁷Rb 5²S_1/2 → 5²P_3/2 → 7²S_1/2, (c) ⁸⁷Rb 5²S_1/2 → 5²P_3/2 → 5²D_5/2. (d) Difference in absorption due to two different velocity groups of atoms: v = 0 m/s and v = +10 m/s for the three different cases as mentioned in the figure. Ω₁ = 1 MHz and Ω₂ = 10 MHz.
