Paper Abstract

Model calculation of second order susceptibilities for FA color centers in wide band gap materials are reported. The second order optical nonlinearity in crystals of alkali halide due to FA color centers evaluated theoretically. The density matrix formalism is employed and the equation of motion is solved by second order perturbation to evaluate the nonlinear optical susceptibilty for second harmonic generation as well as frequency mixing. It is found that the system shows large resonance-enhanced second order susceptibility (~10-16 mV-1) for color center concentration of ~1023 m-3. A scheme of phase matching in terms of anomalous dispersion of the centers and coherent length are discussed.
