The output could always be run through a set of cylindrical lenses to circularize the beam and improve the power density.. if the price drops enough in the future I could see it being worth it if the total price for the diode and lenses could be reached for around $200. Worth it for me, anyways.. but at ~$500 for the diode (if that is what it currently costs) and $70 for the lenses.. hell no ;-)If it's this diode > https://www.lasertack.com/en/1w-405nm-laser-diode-hl40033g
If it's the diode linked above then it is multi mode and typical divergence is 13/42 where as the NDB7875 is typical 14/44 so it's a long way from our beloved single mode 405nm disc burners.
It would look ok in a pointer, but the spot at 100 meters would be a big bar rather than a small spot.
I don't see it being worth the price.
p.s. I am not complaining, just sharing an opinion/info. " Calling it like I see it. "
