Abstract

Very efficient stable optical pumping of an argon metastable atom beam is achieved using a frequency-modulated multimode dye laser. Frequency modulation is accomplished by rapidly oscillating the laser output coupler using a piezoelectric translator. This technique appears attractive for use in optically pumping a wide variety of atomic species.

(a) SG profile for a mixed Ar(3P0,2) beam with no optical pumping. The 3P0 contribution is indicated by the shaded region. (b) SG profile obtained following optical pumping with RHCP 811.5-nm radiation from the frequency-modulated laser. The arrows indicate the expected peak positions for atoms with different values of MJ.

Percentage of 3P2 atoms that remains in states of negative MJ following optical pumping with RHCP radiation as a function of the peak-to-peak amplitude of the voltage applied to the PZT. The vertical extent of each data point indicates the change in this percentage observed at each amplitude over a period of ~15 min.

Percentage of 3P2 atoms that remains in states of negative MJ following optical pumping with RHCP radiation, both with and without a drive voltage applied to the PZT, as a function of the intensity in the optical pumping region. The vertical extent of each data point indicates the change in this percentage observed at each intensity over a period of ~15 min.
