Summary
Infrared tunable diode lasers have been used in recent years as fast and sensitive detectors of trace gases at the ppbv level in ambient air or in reaction chambers. Their sensitivity however, is frequently limited by a periodical noise mainly arising from the laser source and the optical surfaces located within the source to detector path. In this paper, post detection data handling techniques for improvement of the signal to noise ratio in second harmonic spectra are presented together with some experimental results.
