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.
