A highly polarized atomic 23Na beam is produced by optical pumping using either a multimode cw dye laser or a single mode ring dye laser followed by a double pass acousto‐optic modulator. Electron spin polarizations of 0.72 to 0.90 are obtained.

Optical pumping by a single-frequency cw ring dye laser of thick sodium vapor targets ($\mathrm{NL}>{10}^{13}$ atoms/${\mathrm{cm}}^{2}$) without buffer gas has been investigated for application in a polarized ion source. The atomic polarization of the sodium was determined from the optical rotation of a second dye laser tuned midway between the $D$ lines. Rate-equation calculations reproduce the experimental data and predict very high polarizations ($P>~0.8$) with the use of one or more single-frequency dye lasers in thick alkali-metal vapor targets.
