Beamage-M² User Manual Revision 6 18
5.1.2. M
2
Advanced button
The M
2
Advanced button , under the M
2
Open button , activates the advanced M
2
mode. This mode can be
used to measure the M
2
factor of nearly Gaussian laser beams. It must be used carefully as it can return
erroneous values if the beam undergoes many modifications along its path. As most of the measured
beams emerge from laser systems in which beams are transformed in many ways, ones most likely
measures the M
2
factor of laser systems rather than laser beams. For this reason, by default, the M
2
Advanced button is inactive.
