摘要
Nonlinear level anticrossing effects have been observed in saturated absorption in transitions in the ν4 band of POF3 by the method of laser-Stark spectroscopy. The anticrossings occur as narrow additional absorptions superimposed on the Doppler-broadened transitions. From the resonant fields of the anticrossings, values of A0-B0 have been calculated which agree well with values obtained previously. The widths of the anticrossings were found to be independent of sample pressure in the 10- to 50-m Torr range. A procedure for calculating the lineshape for level crossing or level anticrossing that has a greater range of validity than the conventional perturbation theory is described. © 1979.
