Efficient Quantum Memory Using a Weakly Absorbing Sample
A light-storage experiment with a total (storage and retrieval) efficiency eta = 56% is carried out by enclosing a sample, with a single-pass absorption of 10%, in an impedance-matched cavity. The experiment is carried out using the atomic frequency comb (AFC) technique in a praseodymium-doped crystal (0: 05% Pr3+: Y2SiO5) and the cavity is created by depositing reflection coatings directly onto t
