Figure 10From: Polychromatic atom optics for atom interferometryMonochromatic symmetric LMT scheme. Due to the large pulse bandwidth (\({\approx} 19~\text{MHz}\)), if no arm is put into a dark state and no particular Doppler shift compensation is applied, each pulse will act on both arms of the interferometer with good efficiency and impart \(2\,\hbar k\) of momentum splitting—resulting in a symmetric schemeBack to article page
