Coherent beam combination at far field using four Gaussian laser sources

    • krmukesh94

      I’m trying to design a 4-beam Coherent Beam Combining (CBC) system, where the beams coherently combine at a far-field location to form a diffraction-limited spot (as shown below). I'm using a DLL Source with Gaussian beams and a detector at the target, but I’m not seeing a diffraction-limited spot at the target.

      Can someone help me troubleshoot this? Do I need to include a lens or some other optical element to achieve the desired focusing?
