A New Femtosecond Laser‐Based Tomography Technique for Multiphase Materials

A new tomography technique for image 3D nm-scale material features in mm3 volumes has been developed. The technique employs a femtosecond laser for layer-by-layer material removal at rates 4–5 orders of magnitude faster than comparable serial sectioning techniques. The technique can be applied to a wide range of multiphase materia ls and an example of its application for imaging of TiN particles inhomogeneously dispersed in a metallic matrix is given.
