A partially mirror coated parallelepipedal form is oriented to divide collimated beams along the longitudinal axes from a plurality of diode lasers arranged side-by-side along their transverse axis. The divided partial beams are subsequently recombined and arranged side-by-side along their transverse axis using the same rhomboidal form, where the parallelepipedal form and the polarization state of the collimated diode laser beams are oriented to minimize the insertion loss of the device. The side by side arranged partial beams are further coupled into an optical fiber positioned downstream of the parallelepipedal form to deliver a beam with high optical brightness.
