Effective optical quadrupole traps and a planar array of optical wells based on the interference of two optical beams are proposed. Due to this interference a sort of variety distributions are created with intensity maxima and minima that can be used to trap atoms that have transition frequencies appropriately detuned from the frequency w of the light. This technique assists to avoid some undesirable effects of single beam interaction such as destabilizing dissipative force as well as it enhances the magnitude of quadrupole force. In particular, the mutual coupling of two co and counter-propagating Hermite-Gaussian light beams is presented. Both configurations could be turn out to make quadrupole interaction more exploitable to manipulate the spatial position of trapped atoms..
