摘要： A wavelength converter comprising an arsenic sulfide (As—S) chalcogenide glass fiber coupled to an optical parametric oscillator (OPO) crystal and a laser system using an OPO crystal coupled to an As—S fiber are provided. The OPO receives pump laser radiation from a pump laser and emits laser radiation at a wavelength that is longer than the pump laser radiation. The laser radiation that is emitted from the OPO is input into the As—S fiber, which in turn converts the input wavelength from the OPO to a desired wavelength, for example, a wavelength beyond about 4.4 μm. In an exemplary embodiment, the OPO comprises a periodically poled lithium niobate (PPLN) crystal. The As—S fiber can include any suitable type of optical fiber, such as a conventional core clad fiber, a photonic crystal fiber, or a microstructured fiber.

摘要： A Fourier-Transform Infrared (FTIR) spectrometer for operation in the mid- and long-wave infrared region (about 2-15 micron wavelengths) is disclosed. The FTIR spectrometer is composed of IR-transmitting fiber and uses a broadband IR source. A fiber stretcher is provided to provide a path difference between a first path and a second path having a sample associated therewith. Stretching of the fiber provides a path difference sufficient to generate an interferogram that can subsequently be analyzed to obtain information about a sample. A method for use of the apparatus of the invention is also disclosed. The method involves stretching of an IR-transmitting fiber to create a path difference sufficient to generate an interferogram. Various aspects of these features enable the construction of compact, portable spectrometers.

摘要： A hollow core photonic bandgap chalcogenide glass fiber includes a hollow core for passing light therethrough, a Raman active gas disposed in said core, a microstructured region disposed around said core, and a solid region disposed around said microstructured region for providing structural integrity to said microstructured region. A coupler can introduce at least one light signal into the hollow core of the chalcogenide photonic bandgap fiber. The method includes the steps of introducing a light beam into a hollow core chalcogenide photonic bandgap glass fiber filled with a Raman active gas disposed in the core, conveying the beam through the core while it interacts with the gas to form a Stokes beam of a typically higher wavelength, and removing the Stokes beam from the core of the fiber.
