WebIt is also double the Rayleigh distance. The Rayleigh length is defined as the distance for which the beam radius is smaller or equal to √2 times the radius at the waist. So, when a focal length is small compared to the incident beam size, the depth of field tends to be small and vice-versa. Finally, M² corresponds to the quality factor.
