Transport Mean-Free-Path in K 5 Bi 1-x Nd x (MoO 4 ) 4 Laser Crystal Powders

The transport mean-free-paths in K 5 Bi 1-x Nd x (MoO 4 ) 4 laser crystal powders were determined by using the diffuse reflectance and transmittance of the powders and the absorption coefficient of the crystal materials. Similar results were obtained from both methods.
