    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.

    Abstract: Embodiments of the present invention are directed to a nuller that is used to significantly reduce or eliminate a monochromatic radiation signal within a polychromatic object field. In one embodiment, a method of nulling a coherent light from a light beam having the coherent light and an incoherent light comprises collimating the light beam having the coherent light and the incoherent light, and destructively interfering the coherent light to null the coherent light with no destructive interference of the incoherent light so as to project the incoherent light without the coherent light.

    Abstract: The invention provides an apparatus for measuring the physical properties of a sample by optically monitoring the response of the sample to illumination by ultrashort optical pulses. The apparatus is a common path optical interferometer of a Sagnac type that can measure physical properties at normal incidence, i.e., a single-arm Sagnac interferometer featuring two beam splitters. Measurement is performed in such a manner that a sample is excited by a beam of ultrashort optical pulses, and variations in intensity and phase of another optical beam are detected. This enables a wide range of measurement of physical properties such as thickness, sound velocity, and thermal properties of substances.
