Abstract

A new scheme of photo-acoustic Raman spectroscopy (PARS) and coherent anti-Stokes Raman spectroscopy (CARS) by replacing the tunable laser with Raman shifter is proposed. Detection limit of ppm order can be attained for H2 or CH4 in the atmosphere. Because of simple construction, these techniques are useful for continuous monitoring of atmospheric species.
