    Abstract: Method and apparatus for detecting, by absorption spectroscopy, an isotopic ratio of a sample, by passing first and second laser beams of different frequencies through the sample. Two IR absorption cells are used, a first containing a reference gas of known isotopic ratio and the second containing a sample of unknown isotopic ratio. An interlacer or reflective chopper may be used so that as the laser frequencies are scanned the absorption of the sample cell and the reference cell are detected alternately. This ensures that the apparatus is continuously calibrated and rejects the baseline noise when phase sensitive detection is used.

    Abstract: A micro-Raman device includes a first laser light source, a second laser light source, a first holder, a second holder, a first ND filter, and a second ND filter. The first laser light source and the second laser light source generate first laser light of a first wavelength and second laser light of a second wavelength, respectively. The second wavelength is different from the first wavelength. The first laser light and the second laser light proceed in a second direction orthogonal to a first direction while being separated from each other in the first direction. The first holder and the second holder are arranged overlapping each other in the second direction.
