…setup include a beam expander to enlarge the raw output of the laser, a pair of computer controlled galvanometer mirrors to move the beam in two axes (perpendicular to the optical axis), and then a scan lens to focus the radiation on the work surface. This method enables the laser beam to rapidly…

McCauley at Ophir-Spiricon explains,
the beam is first properly sized and attenuated using beam expanders and reducers, microscope objectives, and bulk
absorption filters. The resulting camera
signal is then analyzed for beam size
and roundness, divergence, and visual
