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.
Claims6
A phase-preserving amplification system for stellar interferometers comprising:
- a first crystal configured to receive an optical signal from a first source;
- a second crystal configured to receive an optical signal from a second source;
- at least one pump configured to input a high energy field into said first and second crystals, thereby amplifying said received optical signals;
- a beam combiner configured to receive and combine amplified signals from said first and second crystals;
- and
- a data collection element configured to receive collect said combined amplified signals.
A phase-preserving amplification system for stellar interferometers comprising:
- first and second crystal means for receiving an optical signal from a first and second source, respectively;
- pump means for inputting a high energy field into said first and second crystal means, thereby amplifying said received optical signals;
- beam combiner means for receiving and combining amplified signals from said first and second crystals;
- and
- data collection means for collecting said combined amplified signals.
