…caution when projecting an expanded laser beam
with a mode cup. The expanded beam is sufficiently intense to
cause severe eye damage.
For more precise measurements, a beam scanner, spectrum analyzer
or M2 meter such as the Coherent ModeMasterTM Beam Propagation
Analyzer can…

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

measured at that cut plane gives the second constant, and the diameter measured at the front cut plane 2WD gives the third constant.
The third constant is the diameter of the beam expanded over a

…width expands to an unacceptably high level).
Finally, there is another, more subtle effect
namely, that when a flat object is placed perpendicular to the path of an expanding laser
beam, the edges of the beam must travel
slightly farther to reach the object than
