A memory system for storing information in the frequency domain at room temperature involves the use of an Alpha diketone/ polymer host material system. A specific example is 3 percent biacetyl (BA) in polyemthylmethacrylate (PMMA). Exposure of this material system to a Kr/+/ or Ar/+/ laser line decreases the overall BA absorption. But in the wavelength region of the laser line this absorption decrease is less than in other areas. The net result is an absorption line with spikes at the laser irradiation frequencies. These spikes can be used to store information in the frequency domain.
