摘要：

Methane detection with a new arrangement of photoacoustic Raman spectroscopy has been carried out with self seeding of the Stokes beam generation. It employs only one fixed frequency pulsed laser source, the light of which is focused into a Raman cell, filled with the same gas to be detected. Both fundamental and Stokes shifted beams are sent through a carefully designed photoacoustic cell, resulting in a detection limit of 100ppm methane in N-2.
