This parameter - defined as M squared - is one of the multi-mode operating features of an ytterbium laser. I could not find a good English definition of Beugungsmasszahl anywhere. Thanks.

German term (edited):
Beugungsmaßzahl
Selected
beam quality factor
Your source term is misspelled, should be "Beugungsmaßzahl".
This is called the beam quality factor or beam quality product. Just google it.

I have to correct myself: beam quality product would be wrong here. Sorry.

Info
Beam Propagation Measurements according to ISO 11146 standard disclose beam quality and describes it as a single value either the Times-Diffraction-Limit Factor M2 (also known as beam quality factor or beam propagation factor) or its reciprocal Beam quality K = 1/M2 whereas the beam quality K is direct proportional to the quality level (K=1 optimal, decreasing for worse quality), its reciprocal value M 2 (M2=1 optimal, increasing for worse quality) is used more often. Please do not confuse beam quality (K≤1) and times-diffraction-limit factor (M2≥1).
