M2-factor of Hard-edge Apertured Laguerre-Gaussian Beams-Self-convergent Beam Width Method and Comparison with the Symptotic Analysis
The self convergent beam width method is used to study the beam parameter propagation and M 2 factor of two dimensional hard edge diffracted Laguerre Gaussian beams. The results are analyzed an compared with those calculated by using the asymptotic analysis. It is shown that essentially the self convergent beam width method is based on the truncated second order moments determined by the power fraction and the two correspondence between the two methods is discussed.
