A suggestion for you.
Do some research before posting these questions.

On this forum you'll get negitive rep for asking things that are so easily searchable.

You've pm'd me already ~13x times asking for info that was easily accessible on our forums.
This is only slightly annoying...
No one in their right mind will sell a high power laser to someone whom comes across as being a liability (underage/immature).

Now I am giving you a warning. Others here will take great offense to this sort of abuse of private messaging and not be so kind.
You earned your first negative rep point.
I will undo this when I see you start posting more intelligently.
Thank you.

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

old chinese proverb: If you see the faint 808nm red light, then your retina is already fried.

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.

joke post based on dark suckers ;-)
808nm is dangerous - that's no joke !!!

True.. 808nm isn't terribly useful as a laser unless you're using it as IR illumination or powerful enough to do some cutting.

btw, I don't mind people asking questions. I do mind it when people flood my pm box with question after question that can be found on the forum.

I'm not into spoon feeding info.
