A selective two‐step process is described for the photoionization ofF2centers. An electron trap density no greater than that of the originalF2center population is required for ∼100% ionization, and only modest light intensities are required (I∼10 W/cm2or less). Certain divalent transition‐metal ions have been found to make excellent traps. The two‐step process has allowed the production ofF+2center densities ∼1018/cm3, as needed for the construction of efficient lasers.
