Electro-optic combs operating at gigahertz pulse rates have enabled a dual-comb spectrometer capable of acquiring data at exceptionally high speeds to perform linear absorption spectroscopy on gases of different pressure. Though the experiments are only cursory demonstrations, the results suggest that the advanced spectrometer has potential use in chemical studies in high-pressure environments, such as in power plants and jet engines, and in making spectroscopic measurements of fast and nonrepeatable events.
As the spectrometer can measure a full spectrum in seconds, according to the team responsible for developing it, other applications include those that perform quality-control functions for pharmaceuticals or semiconductors on a…READ MORE
