Webbut the Rayleigh range for the real beam is shorter than the embedded Gaussian by a factor of M² (because the Gaussian diverges more slowly). Relationship to ISO 11146 ¶ When … WebThe FWHM corresponds to the distance between the two points closest to the peak that have 50% of the maximum irradiance or intensity. Some people prefer using other percentages of a beam’s maximum intensity to define its width. A common one is 13.5%, which leads us to our next beam diameter definition: 1/e 2.
