Earlier-discovered weak satellites of the superfine structure of the saturated absorption spectrum of SiF4 in the range of oscillation frequencies of a low-pressure CO2 laser operating at P(38) line of 9.7-µm band are investigated experimentally. The amplitude of the satellites is found to increase relative to that of resonances of the multiplet itself with an increase in the laser power. Within the experimental error, the relative amplitude of the satellites is independent of SiF4 gas pressure. Possible interpretations of the satellites are discussed.
