1. Beamage-M2

1.1. Introduction

The M

factor can be considered as a quantitative indicator of laser beam quality. In terms of propagation, it is

an indicator of closeness to an ideal Gaussian beam at the same wavelength. Paired with a Beamage-3.0 beam

profiling camera, the Beamage-M2 module can provide Real-Time M

measurement directly in the PC-Beamage-

3.0 software. The calculations are based on the second order spatial moments and therefore are fully compliant

to the ISO 11146 and 13694 standards.

Unlike other M

measurement systems, the Beamage-M

can measure the propagation parameters of a laser

beam without the need of any moving part, providing calculation of the M

factor in less than a second. This

condition allows the possibility to do on-line monitoring. Its modular design allows users who only want to

measure the energy or intensity spatial profile of their beam to remove the Beamage-3.0 from the M

module

and use it as a simple beam profiler.
