Just for those that have not "seen" an IR Laser in action - here's a (corny commentary) vid with two demos....

hahahahaha !
No the beam is invisible, due to the wavelength - 808nm is in the ifra-red range. The fiber optic cable is just the "colliminating optics" for this type of diode. The diode itself is most likey either a C or an A mount diode, encased in the brass housing for heatsinking. I believe this originally came out of a peice of medical equipment - maybe for cataract surgery, or lasik, or something of that nature - completely guessing though !
It is pretty cool - I may tear apart my 5mw "nose hair clipper" greenie to see if I can use the crystals and see what the power range I can make would be !

Yeah - I gotta try to dig out my IR webcam from my computer room/office/mess ! I just moved in not too long ago - and the computer room is still mostly boxed up - it is buried in there somewhere - pretty nice little webby, though - has 32 IR LED's for night time illumination ! Yeha, and the camera on my cell doesn't work -some wort of software error - It is just a pain in the A$$ to take it in to the office to get looked at -they take FOREVER.

Maybe I should just Dremel open a 50mw instead ? I have one that the threads stripped on - and will not close any longer - I could open it up like I did for my daughter's class ! That may be a this weekend project.....
