| Abstract: | The refractive index of coherently driven rubidium vapour is experimentally investigated in a three-level cascade configuration using a selective reflection technique. The maximum measured resonant change in the refractive index is Δn ? 0.1. The selective reflection is accompanied by a four-wave-mixing process that can reach ~90% efficiency. |
