…of beam width is the width at which the beam intensity has fallen to 1/e² (13.5%) of its peak value. This is derived from the propagation of a Gaussian beam and is appropriate for lasers operating in the fundamental TEMoo mode or closely. In reality, many lasers exhibit a significant amount of beam

…of a Gaussian beam is the distance from the beam waist (in the propagation direction) where the beam radius is increased by a factor of 2 (which is equal to a doubling of the beam area). For beams with a non-perfect beam quality, the Rayleigh Range is decreased by a factor which is called the beam

Beam Profile vs. Beam Propagation Beam profilers measure the spatial intensity distribution of a laser beam. However, no matter how accurately and diligently a profile is measured, this information does not predict the intensity distribution elsewhere along the beam path. If the propagation
