We numerically calculate forces acting upon a spherical microobject in a new family of paraxial laser beams. When propagated in homogeneous space, these beams retain their structure up to scale. It is numerically shown that when the mode’s azimuth number remains unchanged, while the radial number changes severalfold, the force exerted upon the microbead of diameter less than the width of the mode’s bright diffraction ring changes in nearly the same proportion.

Key words:
hypergeometric beams, paraxial laser beams, optical forces, spherical microobjects, diffraction ring.
