Abstract: A dual source system and method includes a high power laser used to determine elements in a sample and a lower power device used to determine compounds present in the sample. An optical subsystem directs photons from a sample to a detector subsystem after laser energy from the laser strikes the sample along an optical path. After energy from the device strikes the sample protons are directed to the detector subsystem along the same optical path. The detector subsystem receives photons after laser energy from the laser strikes the sample and provides a first signal, and receives photons after energy from the device strikes the sample and provides a second signal. A controller subsystem pulses the high power laser and processes the first signal to determine elements present in the sample, energizes the lower power device and processes the second signal to determine compounds present in the sample.

Abstract: A Raman analyzer for analyzing light emitted from a Raman cell is provided that has a beam splitter configured to split the light emitted from the Raman cell into a first beam and a second beam. An atomic vapor filter can be used to filter a Raman scattered line from the first beam and a chopper system can periodically interrupt the first and second beams that are directed towards a photo detector, which can convert light from the first and second beams into an electrical signal. The signal output from the photo detector can optionally be amplified, digitized, Fourier filtered, and/or subjected to Fourier analysis.

Abstract: The invention disclosed here teaches methods to fabricate and utilize a non-dispersive holographic wavelength blocker. The invention enables the observation of the Raman signal near the excitation wavelength (˜9 cm−1) with the compactness of standard thin film/holographic notch filter. The novelty is contacting several individual volume holographic blocking notch filter (VHBF) to form one high optical density blocking filter without creating spurious multiple diffractions that degrade the filter performance. Such ultra-narrow-band VHBF can be used in existing compact Raman instruments and thus will help bring high-end research to a greater number of users at a lower cost.
