  • Photothermal interferometry apparatus and method
    Patent number: 10732097
    Abstract: A photothermal interferometry apparatus and method for detecting a molecule in a sample, in particular for detecting a trace gas species, comprising: a Fabry-Perot interferometer with a first mirror, a second mirror and a first cavity for containing the sample extending between the first and the second mirror, a probe laser for passing a probe laser beam through the first cavity of the Fabry-Perot interferometer, an excitation laser for passing an excitation laser beam through the first cavity of the Fabry-Perot interferometer for exciting the molecule in the sample, and a photodetector unit for detecting the transmitted probe laser beam passed through the first cavity of the Fabry-Perot interferometer.
