What is it about?
This paper describes a system that easily and accurately measures a laser's M-square value with a high degree of repeatability. It is self-calibrating and is fully compliant with the ISO 11146-1 (2005) document.

Why is it important?
Most mainstream M-square measurement system have poor repeatability and therefore a system that has a high degree of repeatability and is easy to use, is of great interest and value to the laser industry.
