Mode Master White Paper July 2011 final.pdf

…ratio of a beam's actual divergence to the divergence of an ideal, diffraction limited, Gaussian, TEM00 beam having the same waist size and location. Specifically, beam divergence for an ideal, diffraction limited beam is given by: 0 w l theoretica , Where the divergence of an actual beam is given…

…the real beam diverges faster, then it must diverge faster by the factor
M2
If both have the same divergence angle but the real beam has a larger
waist, then it must be larger by the factor M2
If the real beam is everywhere larger than the ideal beam by
, then the divergence

…the laser cavity affect beam parameters. These variations make laser beam measurement essential for many processes. 5 Determine beam divergence fast and easy. 1 Laser beam profilers are typically used to measure beam diameter and spatial intensity distribution. By measuring beam profile at more than…

…3
Divergence
Since Gaussian beams follow the
diffractive principles, we cannot achieve
a perfectly collimated beam and the
divergence of the beam is dependent
on the waist size that is set by the
optical system.
Far field divergence of a laser beam
