Transport mean free path in K5Bi1-xNdx(MoO4)4 laser crystal powders

In this work, we calculate in two different ways the transport mean free paths in K5Bi1-xNdx(MoO4)4 (x = 0.05, 0.2, 1) laser crystal powders by using the diffuse spectral reflectance and transmittance of the powders and the absorption coefficient of the crystal materials. The theoretical calculations have been made by assuming a diffusive propagation of light in these materials. Similar results have been obtained from both methods
