a–c Beam size (FWHM) change as a function of the gradient and scattering forces obtained via numerical simulations using a 350-mW input power and neglecting random scattering effects, where one observes the change in beam size when either the gradient or the scattering force is “turned off”. d, f Side-view of the beam propagation and e, g corresponding output transverse intensity patterns after propagating through an RBC-like random scattering medium at low (d, e) and high (f, g) beam power. The beam side-views and output intensity patterns are normalized with respect to their respective maximal input powers
