I tried this this morning after pulling an all nighter improvising to make a laser from my drive because I don't have any "real" parts if you will. It works though and it makes the glass look sweet.
405nm or 400nm is no big difference it's close to UV. It can still pass glass wich starts absorbing around 400-350nm (even at 350nm part of it would pass the glass).
PS: UV lasers are way less fun than visible ones. Believe me i have to work all kinds of lasers in my lab...
The point I was trying to make was that it isn't UV. The diode you used is 405nm; in the violet part of the spectrum. UV truly starts at around 400nm. UV would be REALLY dangerous in a laser, much more if it was portable.
You can get ones in the 330nm range but as you say.... I would be afraid of messing with them. Same as the high powered IR one... Too dangerous for me
IR isn't that dangerous. If you have the proper eyewear, it's not that harmful at all. UV on the other hand, will do more than burn your skin, if it's UVB or UBC, it has a possibility of causing cancer.
Got mine to work - but Dads blue ray player wont read disks any more..... He likes the laser effects though

it is probably half UV the UV spectrum usually starts at 400nm. 405 is a violet laser

...thats not uv cuz uv doesnt **** pass through glass.
that laser is near to uv but not uv.

it is 405nM that is what it is...

@xarran hey wise guy, if it were true UV you wouldn't be able to see it. Near UV light is colloquially referred to as UV.

I wish we had UV lasers in portable form...of coarse, we would all probably get cancer. :O

It IS Portable!!!! It came out of an HD-DVD player and runs on a nine volt battery

im sure it gives of a very very small amount of UV rays with the violet laser(even though a lasers supposed to be only 1 wavelength)

what do u count with nm
priklodrakoulas 2 years ago
Wavelength one nanometer is 1X10-9th meter
dj4mc 2 years ago
so u mean the size of the ray?
priklodrakoulas 2 years ago
No the wavelength of the light. based on its frequency. Shorter the wavelength, the higher the frequency.

thats awesome, i will have to try it!
