Description of optical tweezers: Ponderomotive force?

  1. Oct 18, 2013 #1
    It is mentioned that in optical tweezers the dielectric particles are attracted to the gradient of the laser's electric field.
    Is this mechanism the same as the ponderomotive force?
    If so, why is this connection not made directly?
