Abstract
A formula for frequency-dependent optical second-harmonic susceptibili ties for insulating crystals, including local-field corrections, is pr esented. In analogy to a formula given previously for the static limit , the formula is analyzed in terms of ''virtual electron'' (ccv) and ' 'virtual hole'' (vvc) terms to obtain a numerically stable form. Numer ical results for GaP and GaAs agree with most of the experimental valu es suggested in a recent review article by Roberts. Miller's DELTA(M) is predicted to vary by 13% from the laser lines at 10.6 to 1.32 mum f or GaP.
