Abstract
The dependence of the yellow conical emission angle on pump laser inte nsity is studied experimentally in dense Na vapor under near-resonant one-photon excitation of the sodium 4(2)P levels. A numerical model de veloped to describe mechanisms involved in the conical emission genera tion processes indicates that the saturation observed is due to the op posite angular tuning of the near-infrared and yellow conical emission generated in the same process. The mechanisms responsible are assigne d to (self)induced phase modulation processes of the waves involved.
