RP Photonics Encyclopedia - beam radius, laser beam where the beam radius w is the distance from the beam axis where the optical intensity drops to 1/e 2 ( 13.5%) of the value on the beam axis. At this radius, the electric field strength drops to 1/e ( 37%) of the maximum value. The usual formula symbol of the beam radius is w.Some authors use instead, but that may be confused with an angular frequency.
