| Abstract: | he influences of linear photoacoustic signal on the sensitivity,detect-ing limit and frequency shift of photoacoustic Raman spectroscopy is discussed,Ageneral expression of linear photoacoustic signal in CW and pulsed photoacoustic Raman spectroscopy is derived.Further more the signal-to-noise ratio and de-tecting limits are also given.the temporal Gaussian laser beam exerting an influ-ence on the Raman transition probability is also discussed. |
