…important where outside the laser cavity the beam is analyzed. There are three basic regions each with its own mode characteristics, the Near Field, the Rayleigh Range, and the Far Field. For diffraction-limited beams, the Rayleigh Range ZR is determined by its waist radius R0 and laser wavelength (ZR = ·…

…ratio of actual beam divergence (), shown in blue, to the divergence () of a perfect Gaussian beam, shown in green, having the same waist size and location. The waist location (Z0) and the waist diameter (2W0) must coincide for this calculation. M2 is defined as the ratio of a beam's actual divergence…

…because M² is the product of a beam's
minimum diameter and divergence angle. It is a measure of how well photons in the beam are localized in
the transverse plane as they propagate. Acc. to the uncertainty principle, there is a minimum possible
product of waist diameter times divergence, corresponding…
