Abstract
This paper gives a detailed summary of the International Standardization Organization working draft concerning measurement methods for laser beam width, divergence and propagation factor. Some of the important reasons for the multiple methods included in the draft are presented. A comparison of the differences between various definitions of, and methods for, measuring beam width is given. The document is not yet final and comment on the definitions and methods proposed is invited.
