Comparison of collisional redistribution and emission line shapes
Michael G. Raymer, John L. Carlsten, Goran Pichler
The authors have studied collisional redistribution of near-resonance radiation in thallium vapour caused by collisions with argon buffer gas. Electronic Raman scattering and collision-induced fluorescence were spectrally resolved, both to the weakly populated metastable 6 2 P 3/2 level in thallium. Thus the problem with radiative trapping encountered in previous experiments is partially avoided. By measuring the total collision-induced fluorescence as a function of the incident laser frequency, the absolute collisional redistribution line shape is obtained.
