Abstract
A high sensitive chemical analyzer of molecular gases is presented. It's based on measurements of high resolution molecular absorption spectra obtained with infrared tunable diode lasers (TDL). To transmit radiation from lasers to an analytical cell and back to detectors, infrared fibers with low optical losses are used. A multipass optical cell is used to enhance the essential sensitivity of the sensor. Various gaseous molecular objects could be detected by this analyzer due to the wide spectral range of available TDLs and fibers. Use of fibers for laser transfer could provide remote monitoring and multicomponent mixture analysis and evanescent spectroscopy of gases in the near future.
