The raman shift
WebbDifference frequency mixing (DFM) of high power single-spatial-mode near-IR laser diodes is an attractive method ofproducing tunable mid-infrared radiation. Such mid-IR sources operate at room temperature and can be reduced to compact size for use in a broad range of spectroscopic and commercial gas sensing applications. There have been several … WebbThe Raman Spectroscopy Principle. When light interacts with molecules in a gas, liquid, or solid, the vast majority of the photons are dispersed or scattered at the same energy as …
