英文摘要	In this letter, we report on the development of an innovative multi-gas sensor based on multi-resonator photoacoustic spectroscopy (MR-PAS). This novel technique offers multi-laser operation to simultaneously monitor multiple pollutant species using a single photoacoustic spectrophone. A photoacoustic cell including three acoustic resonators operating at different resonant modes was designed, a single microphone was used to listen the photoacoustic signal in each resonator simultaneously. Feasibility and performance of the innovated MR-PAS sensor was demonstrated by simultaneous trace gas detection of H2O vapor, CH4 and CO2 using three near infrared distributed feedback diode lasers. 1 sigma normalized noise equivalent absorption coefficients (NNEA) of 2.1 x 10(-9) cm(-1) W/Hz(1/2), 2.9 x 10(-9) cm(-1) W/Hz(1/2) and 6.5 x 10(-9) cm(-1) W/Hz(1/2) were respectively achieved for H2O, CH4 and CO2 detection at normal atmospheric pressure.
