ABSTRACT:
A phase-preserving amplification system for stellar interferometers is disclosed. In one embodiment, a pair of crystals are provided that are configured to receive an optical signal from a source such as a telescope. A pump inputs a high energy field into the crystals, amplifying the optical signals using optical parametric amplification (OPA). A beam combiner receives and combines the amplified signals and a data collection element collects the combined amplified signals.
