WebJan 10, 2016 · It is well known that in the presence of a ring cavity the light scattering from a uniform atomic ensemble can become unstable resulting in the collective atomic recoil lasing. This is the result of a positive feedback due to the cavity. We propose to add an additional electronic feedback loop based on the photodetection of the scattered light. … WebHere, we address this using a system with incoherent feed-forward loop connectivity, the galactose (gal) system of Escherichia coli.
