WebMar 2, 2006 · In the top curve the EIT resonance is seen together with VSOP and Dicke revival peak. Inset shows the results of fitting: the EIT resonance linewidth is ≈ 9 MHz, VSOP linewidth is ≈ 35 MHz. The middle curve shows the case when the coupling laser is blocked, and revival of Dicke-narrowing effect is well seen.
