Doubly dressed states in a ladder-type two-photon, three-level coupling system are observed. The electromagnetically induced transparency (EIT) doublet signal is interpreted as arising from the absorption and gain components of the Mollow spectrum. The separation of the EIT doublet matches the theoretical prediction. A numerical simulation demonstrates that the Doppler velocity group may perturb the light shift from the symmetric center of the EIT doublet. The quantum nature of the EIT system significantly suppresses Doppler broadening.
