Stability of Diode-Laser Spectrometer for Monitoring of OCS, C3H4, CN Molecular Systems Concentrations

Original language description

This paper describes the assessment of infrared detection technique by the Allan variance method. In particular, the results demonstrate how to determine the optimal averaging time in such experiments. The experimental technique is diode laser spectroscopy. Several molecules were studied including stable molecules (OCS, C3H4) and a short-lived free radical (CN). Three types of Allan variance are mathematically defined, and then their behavior is extensively tested on experimental data. Simultaneously, the integral formula for the direct conversion from the frequency to the time domain is used to get results for comparison. The stability analyses were determined by 2000 s measurements. Results show the possibilities of the presented procedure that is going to be used for the evaluation of direct time domain laser frequency stability measurements. Results are focused on the area of influence of the reactivity on the optimal averaging time for the minimum detectable concentration is demon
