Spatial Characteristics and Spatial Transformations
Spatial characteristics describe the transverse intensity distribution of a laser beam—including beam spot size, M² factor, and transverse mode—while spatial transformations refer to optical manipulations such as beam shaping, filtering, and mode conversion to tailor the beam profile for specific applications.
