Abstract

A method includes depositing a plurality of dopant particles within a predetermined region of a transparent material. The method also includes focusing a laser beam along an optical axis to a focal region that overlaps with at least a portion of the predetermined region. The focal region can irradiate at least a first dopant particle of the plurality of dopant particles. The method further includes adjusting a parameter of the laser beam to generate a plasma configured to form an inclusion within the transparent material. The method additionally includes scanning the focal region along a path within the transparent material to elongate the inclusion generally along the path.
