WebBasically, the D4σ diameter is 4 times the standard deviation of the distribution of intensity along the major and minor axis of the beam. It is calculated from the second moment of the beam profile. For a perfect Gaussian beam with no noise in the measurement system, the measured diameters in 1/e 2 definition and D4σ are identical. http://mast-tech.com.tw/semi-definition.pdf
