Abstract
After being baked out to remove absorbed gases, fursed silica cell blanks are cooled from a temperature of around 900.degree. C. to a temperature of around 800.degree. C. over a period of at least two hours. After the blanks are cooled to room temperature, an unsaturated vapor of atoms having an S.sub.o ground state is driven into the cell blanks from a reservoir. The cell blanks and the vapor contained therein are subjected to optical resonance radiation for around four hours at room temperature while the cell blanks are connected to the reservoir. A prescribed vapor density is established in the cell blanks before they are sealed off from the reservoir.
