…is, there are certain defined beam
parameters of a laser source beyond just power or energy that need
to be measured, optimized, or specially monitored. Beam profilers
are important tools used for laser beam characterization.
The two main beam profiler technologies most commonly…

…determining the M² value, the output beam was focused by
an achromatic lens. The beam profile was then recorded along the propagation axis with a
beam profiler (WinCam D). The beam caustic was then fitted to the second moment values of
the beam profiles indicating M² < 1.2 for both…
