Do you own any NUBM44's ?Why single mode reds? Despite the divergence if we could converge 6 44s radially with perhaps one in the center, through a lens at between 10 and 20 feet, that would be effective.
Without beam shaping the divergence is very aggressive, you would be overlapping long thin lines and the power concentration would be poor for all except short range work, at 5 yards ( 15 feet ) a NUBM44 with a G2 lens makes a line over 2 inches long.
NDB7875 diodes would be better for 10 feet, but if you were going to use it for desktop and a working distance measured in inches then NUBM44's could be used, but for converging the beams at any distance measured in feet the divergence would give a poor result.
