A - Experimentally measured and theoretically calculated values of dns dt, the number of Stokes photons per unit time emitted from the atomic vapor cell. For each plot, ns f dt dns dt represents the total number of photons emitted from the cell. The write laser power is varied from 25 mW to 100 mW. B - Experimentally measured and theoretically calculated values of dnAs dt, the number of anti-Stokes photons per unit time emitted from the atomic vapor cell. The experimental pulse shapes correspond to a Stokes pulse with ns 3 photons, and the theoretical curves assume an initial spin wave with nspin 3 excitations and an optical depth of 20. Each curve is labeled with the power of the retrieve laser. Inset - Big Chemical Encyclopedia
