Can anyone explain α0 (linear), β (nonlinear) absorption coefficients and Is (saturation intensity), are these intrinsic properties of the materials?

α0 = O.D/path length, O.D depends on the concentration of the material, So α0 will changes with material concentration. β having relation with α0 in nonlinear optics at low irradiance limit as...
