Yes, all beams will spread from diffraction.   If the beam is extremely
powerful then it may not need to focused as much.   The farfield
diffraction half-angle is ~ wavelength/(diameter of beam waist).  For a
Gaussian laser beam the "diameter" is taken to be pi x beam radius where
the beam radius is measured when the intensity  has dropped to 1/e2 of the
maximum.
