Coherent beam combination at far field using four Gaussian laser sources

  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?

  Hi Subscriber,
  Thank you for reaching out to us! Yes, I believe in this case you will need a lens in order to combine the beams on the target.
  Kind Regards,
  Niki

    How to add phase between the beams ?
