Recently several schemes have been proposed to create the spin-orbit coupling (SOC) of the Rashba-Dresselhaus (RD) type for ultracold atoms illuminated by several laser beams [1]. This leads to numerous interesting phenomena such as a non-conventional atomic Bose-Einstein condensation for ultracold atoms affected by the SOC. Here we explore effects due to the position-dependence of the spatial profiles of the laser fields inducing the SOC. We show that the spatial-dependent laser beams can provide the Lorentz force in additional to the SOC. Subsequently we analyze a combined action of the contributions due to the Lorentz force and the SOC. [1] J. Dalibard, F. Gerbier, G.Juzeliunas, and P.Ohberg.
