Abstract

There is considerable interest in laser optical pumping of atomic vapors as a source of polarized nuclei. [1] Single mode dye laser radiation offers many advantages, but ordinarily the resulting efficiency in polarizing the sample is low because of incomplete Doppler coverage. Recently it has been shown that large nuclear polarizations can be efficiently achieved by means of velocity changing collisions (vcc’s) induced by small amounts of buffer gas. [2] This paper studies the details of this process in the first resonance transitions of Yb, Li, and Na, and demonstrates that velocity thermalizing collisions can cause a Doppler broadened system subjected to monochromatic radiation to respond as if it were homogeneously broadened.
