Abstract

We have investigated some nonlinear optical effects in a series of optical glasses and laser glasses. Using different methods, we have measured the nonlinear refractive coefficient of these glasses. We have analyzed the possible mechanisms resulting in refractive index change in glass and calculated their nonlinear refractive coefficients. We have also discussed the dependence of laser-induced damage and thermo-optical blooming on nonlinear refractive coefficients.
