WebThe absorption coefficient of pure diamond increases rapidly with photon energy, as discussed by Clark et al [81]. Diamond is effectively opaque at photon energies just above the indirect band gap, but data on the band structure were obtained many years ago by using reflection spectra up to 35 eV [82,83].…” WebJan 26, 2024 · The absorption coefficient is, of course, dependent on the concentration of the chromophore. If we want to compare two different chromophores but the samples have different chromophore concentrations, we can divide the absorption coefficient of each chromophore by its concentration in absorbers/cm 3 (note that 1 ppma in corundum is a … WebIntensity-dependent transmission measurements of 310-nm femtosecond pulses show that diamond has a two-photon absorption coefficient of 0.75 ± 0.15 cm/GW, in approximate agreement with universal scaling formulas for two-photon absorption in diamond-structure materials. We then demonstrate that two-photon absorption is strong enough to permit … d6 inc masks
