The purpose of this paper is to report our results on the detection and spectroscopic parameters of carbon monoxide, carbon dioxide and sulfur dioxide using high resolution linear diode laser spectroscopy with pulsed tunable PbS1-xSex homolasers. The parameters of pulsed diode lasers used in spectroscopy for various gases are discussed. The application of the diode laser spectrometer for CO gas detection at ppm level illustrates the sensitivity of the equipment.

Open Path

Abstract By modifying the wavelength of the open path tunable diode laser spectrometer (TDLS) in the near infrared region, theoretical research was implemented to improve the detection limit of carbon monoxide gas. To adjust the correct wavelength in the NIR area, MatLab code was created. Following that, frequency domain measurements were performed in order to extract the second harmonic as an indicator of gas presence. According to the results, the correct wave length in the NIR area is (1584.877 nm), and the lowest limit of CO gas concentration is (0.012 ppb).

Absorption Features

Abstract The absorption spectrum of the Ar-CH4 van der Waals complex was measured for the first time in the 7 μm region. The complexes were produced in a pulsed slit supersonic jet and detected by a tunable diode laser spectrometer with 40 MHz spectral resolution. The strongest absorption features of the Ar-CH4 complex were observed in the spectral region 1310.57-1311.05 cm -1 , located between the Q(l) and the R(0) lines of the ν4 fundamental band of the methane monomer. It was found that the newly detected absorption lines belong to three Q-branches of the Ar-CH4 complex. The transitions of these Q-branches are related to the Q(l) transition in the ν4 fundamental band of the methane molecule, which can rotate almost freely inside the complex. The three Q-branches have been assigned.
