Abstract: Based on Fourier-transform intra-cavity laser absorption spectroscopy (FT-ICLAS) setup reported, a signal differential module is introduced to reduce the noise rising from the fluctuation of the laser power and to improve the quality of the interferogram obtained in the experiment. The capability to do quantitative measurement was demonstrated by recording the atmospheric oxygen absorption near 760 nm. The v=6 local mode stretching overtone spectra of phosphine were recorded with different sample pressure. The pressure caused self-broadening and line shift parameters of this band were achieved.
