Figure 6From: Microwave electrometry with bichromatic electromagnetically induced transparency in Rydberg atomsTransmission of the bichromatic control field with Doppler effect for the counter-propagation (a) and co-propagation (b) cases; (c) is the same as (a) except for \(\Omega _{m} = 0.00125\Gamma \) and (d) is the same as (b) except for \(\Omega _{m} = 0.00045\Gamma \) (inset is zoomed views of central peaks). Other parameters are the same as in Fig. 2Back to article page
