Parameters of saturated absorption resonances of the /sup 192/OsO/sub 4/ molecule in the 28. 46 THz range at low pressures
A high-pressure waveguide CO/sub 2/ laser was used to measure the impact broadening ..delta nu../sub r/0, saturation intensity I/sub sat/, and contrast of /sup 192/OsO/sub 4/ saturated absorption resonances in the 28.46 THz range. Values of these parameters in the pressure range p = 0.5--10 mTorr are given for both a traditional resonance due to a transition from an excited vibrational--rotational state and also for a higher-intensity resonance corresponding to the A/sup 2//sub 2/P(46) transition from the ground state. The parameters ..delta nu../sub r/0 and I/sub sat/ for both resonances are approximately the same in the pressure range under study and for p<1 mTorr they are ..delta nu../sub r/0 (p) = (30 +- 5)p kHz and I/sub sat/ (p) = (15 +- 3)p/sup m/ ..mu..W/cm/sup 2/, where 1
