ABSTRACT:
The spectrophone, in which a gas containing an impurity in an absorption cell is illuminated by an optical beam that is modulated at an acoustic frequency, has an output pressure response at the acoustic frequency in accordance with the concentration of the impurity in the gas. This output is tuned by a magnetic (or electric) field applied to the absorption cell, while the optical wavelength is kept constant. The Zeeman (or Stark) effect of the impurity can thus be used to tune the absorption process of the impurity to a maximum response.
