Abstract:
An investigation was made of the saturation of the molecular absorption in the ν3 band of silicon tetrafluoride SiF4 by the CO2 laser radiation corresponding to the 0001–0200 transition (λ = 9.4 μ). Measurements were made of the coefficients of unsaturated absorption of the P(30), P(32), P(34), and P(36) lines of the carbon dioxide laser radiation. Resonances were observed in the transmission of a weak opposite wave at the wavelengths of all four lines, and the positions of the resonances were determined relative to the central frequencies of the emission lines of the CO2 laser. The parameters of the high-contrast resonances near the centers of the P(30) and P(36) lines were determined. Such resonances could be used to stabilize the emission frequency of the CO2 laser. The measured values of the broadening constants were 4.1 ± 1.5 and 2.6 ± 2 MHz/mm Hg for the P(30) and P(36) lines, respectively. The minimum width of the observed resonances was 0.9 MHz at a pressure of 5.5 × 10–2 mm Hg. It was concluded that SiF4 could be used to achieve a high stability and reproducibility of the emission frequency of the CO2 laser.
