saturated interference spectroscopy saturated interference spectroscopy[′sach·ə‚rād·əd ‚in·tər‚fir·əns spek′träs·kə·pē] (spectroscopy) A version of saturation spectroscopy in which the gas sample is placed inside an interferometer that splits a probe laser beam into parallel components in such a way that they cancel on recombination; intensity changes in the recombined probe beam resulting from changes in absorption or refractive index induced by a laser saturating beam are then measured. |
