Photon echo without a free induction decay in a double-Λ system
We have characterized a novel photon-echo pulse sequence for a double-Λ-type energy level system where the input and rephasing transitions are different from the applied π pulses. We show that, despite having imperfect π-pulses associated with large coherent emission due to free induction decay (FID), the noise added in the echo mode is only 0.2 ± 0.1 photons per shot, compared to 4 × 10⁴ photons in the FID modes. Using this echo pulse sequence in the "rephased amplified spontaneous emission"...[Show more]
