    Abstract: A semiconductor laser diode system may include a single longitudinal mode laser diode and a feedback system that monitors and controls the emission characteristics of the laser diode. The laser diode may include a gain medium and an optical feedback device. The feedback system may include a wavelength discriminator, an optical detector, a microprocessor, and a laser controller. Such a semiconductor laser diode system may be used to produce laser light having coherence length, wavelength precision, and wavelength stability that is equivalent to that of a gas laser. Accordingly, such a semiconductor laser diode system may be used in place of a traditional gas laser.

    Abstract: Apparatus for performing Raman analysis may include a laser source module, a beam delivery and signal collection module, a spectrum analysis module, and a digital signal processing module. The laser source module delivers a laser beam to the beam delivery and signal collection module. The beam delivery and signal collection module delivers the laser source beam to a sample, collects Raman scattered light scattered from the sample, and delivers the collected Raman scattered light to the spectrum analysis module. The spectrum analysis module demultiplexes the Raman scattered light into discrete Raman bands of interest, detects the presence of signal energy in each of the Raman bands, and produces a digital signal that is representative of the signal energy present in each of the Raman bands. The digital signal processing module is adapted to perform a Raman analysis of the sample.

    Abstract: A sensor for detecting material degradation may include an optical fiber and a housing through which the optical fiber extends. An end cap may be affixed to an end of the housing. Light provided through the optical fiber may be reflected off of the end cap back through the optical fiber. The end cap may be made of a material of interest, and may be situated in an environment wherein the material of interest is present. A light source may provide input light through the optical fiber. A portion of the input light may be reflected off of the end cap. A light receptor may receive the reflected light via the optical fiber. A processing unit may be adapted to compare a measured intensity of the reflected light to a threshold, and to initiate an alarm condition if the measured intensity is below the threshold.
