Blindness?^^

Yes I do, more than ever. I'm nowhere near totally blind. My love for them has grown, but changed a bit. I'm no longer very interested in portable lasers or burning things. My photonic interests are now geared towards making the hobby into a self sustaining business (not including only selling hand-helds or related parts).
I'll stop here before I digress too far.:D
 





I think I'd rather be shot in the head with a laser beam than a gun.

Well, as you can see by the title of the post, I haven't got any "deep knowledge" about lasers, but I imagine/believe there should be a laser out there strong enough to blow up your head just as a bullet would.
Right?:undecided:

Yeah, but I doubt it is man portable.

Edit: After further review, I have decided that your intentions can't be all that bad. After all, Pink Floyd is your religion.

^^i read your post about eye damage, and as i'm new to lasers and i bought a 50mW 532 without glasses, i wanted to know how did you use your lasers at the time they damaged your eyes, becouse i want to avoid it, from what i know : 1- Don't burn (without glasses) 2- Be aware reflective surfaces. So, any tip from you would be greaT! THanks :D

To put this difficult to simplify subject as simply as I can:
1) If it leaves spots in your vision, don't look at it.
2) If you catch a direct or specular reflection, of anything over a few mW regardless of wavelength in the dark - you probably did damage.
3) It is unlikely you will be able to tell you have done damage to your vision right away. But it adds up, quickly!
4) When in doubt... JUST DON'T! Once usually isn't all that bad, but are you really only ever going to do this just once?

Thank you for this.

PS I really enjoy lasers, but they do scare the sh** out of me :D
 
Also darts, a BB gun, a hot poker, a spoon, and about a million other things.

This is such a good point. And at least we know exactly what a LASER is going to do when we turn it on. ;) Unlike fireworks, a campfire, a hot grill, a deep fryer etc... With proper safety precautions, I'd say lasers are pretty safe.:beer:
 
im just curious. do you enjoy lasers for burning? the beam? or to collect different colors?
 
Hey Blade, I realize your question is in all likely hood not aimed at me, but just in case it is here is my answer:

Yes+

I'm personally not very atracted to burning, i actually would like to colect "exotic colours" but I'm not willing to spend the $, so overall yea, the beam, thats my choice, why?

While well intentioned, IMO 1 and 2 are a tad paranoid.

1)Headlights from oncoming cars leave spots in my vision. As does the occasional glance at a regular lightbulb... or any source of bright light.

2)Specular reflection, while certainly uncomfortable, are rarely actually dangerous imo. I did tests a while back with a bunch of materials from around my apartment, focusing as much as possible of the specular reflection on thermopile. Considering that the thermopile sensor is actually much larger then pupil... if anything the results were in favor of more danger.

What I would is, off of most matte, and even some seemingly shiny surfaces the amount of light that goes into your eyes is less than 5mW, and significantly less from even short distances.

All that said, looking at dots even on the most common surface around (wall paint) with laser of over 100mW, is IMO uncomfortable.

just curious. cuz i was thinking, lasers would potentially be more dangerous to people who want to burn and want killer beams (like me lol) due to the higher powers thought to be needed.

and yeah, those exotic colors dig deep into your pockets!
