Abstract

An apparatus for generating narrow-band single and multi-photon state with long coherence length is disclosed. The apparatus comprises a laser pump (20) producing laser light, a non-linear optical crystal (30) within an optical cavity (40), wherein the optical cavity (40) comprises at least two mirrors (42, 44); and a tuning crystal (50) situated between the non-linear optical crystal (30) and a first one (42) of the at least two mirrors.
