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. "
