摘要：

Tolerance analysis shows that an efficient M-2 measurement plan is a first cut (beam diameter measurement) at 0.5-2.0 Rayleigh ranges to one side of the waist, which is matched by interpolation between second and third cuts to the opposite side. The waist is measured by a fourth cut halfway between the matched diameters, yielding an easy two-parameter curve fit for M-2. (C) 1998 Optical Society of America.
