WebLaser beams. The limits on focusing or collimating a laser beam are very similar to the limits on imaging with a microscope or telescope. The only difference is that laser beams are typically soft-edged beams. This non-uniformity in light distribution leads to a coefficient slightly different from the 1.22 value familiar in imaging. However ... WebThe beam waist (or beam focus) of a laser beam is the location along the propagation direction where the beam radius has a minimum.
