Hello,I can see some 808nm Laser in O-Like,what's color it's this 808nm ?
Thank's before for your help.

808nm? It look like this:
I think an 808 is black?

If 808nm is Black how you can see the laser at night ?

You can see 808nm at at night....the black 808nm photons cause a sort of black shadow, so the background light is absorbed. With a 808nm beam you actually see the shadow of the beam.
This is exactly the opposite way a torch beam works, the white light photons let through the photons from the background, therfore you can see the beam and background.
Simple physics.

808nm is infrared. You may see some faint dark red. Anyway it isn't very useful as laser.
