抄録

A new technique of photoacoustic Raman spectroscopy (PARS) is proposed and demonstrated for the detection of trace gas molecules in the atmosphere. No tunable laser is required in the proposed method. Only a fixed-wavelength pulsed laser is used as a light source, and a Raman shifter, filled with the same gas as that to be detected, automatically generates the Raman-shifted radiation required for the detection by PARS. In the detection of trace H2 gas in the atmospheric pressure mixture with N2, the detection limit of 3 ppm (3x10-6 in partial pressure) was obtained using a Q-switched, frequency-doubled Nd:YAG laser.
