I can't help but laugh at that , mfo!

What exactly is a 'douche' and why is it so offendive?

Technically, this is what a douche is.
Douche - Wikipedia, the free encyclopedia

In slang, it's more or less another word for an a-hole.

examples I could find in just a few minutes.....

Well, i try to have a nice discussion about lasers and you people turn it into a clusterfuck.

So I'm buying my first laser to make a fun light display synced to music. ( Just mount a mirror on a small speaker and aim the laser at the ceiling ) I'm wondering which of these is safer / brighter, a:

20mW Green DPSS laser module

or a

140-150mW 650nm Laser diode module?

Both from Sunclan Lasers

I think I heard that DPSS could injure your eyes quicker since they're pulsed. I'm planning on being pretty safe, but PERMANENT damage freaks me out. Am I being too worried for these 2 lasers?

So a 50mW would be relatively safe? How long could that o-Like 50mW Green run, as far as heat goes? Would it need a heat sink to run continuously?

You should probably do some reading around here before you go buying a Class IIIB laser.

Well basically that's what I'm wondering. Specular reflections: How bad would it really be (I'm not planning on being any less safe here, just wondering) if oops the beam hit the cieling fan brass and reflected into my eyes for a split second, any permanent damage?

If it is moving fast, No.

What?? light reflected off metal hardware will be harmless??? OMG NO!!!

I call BS....

My Rayfoss 500mW shipped today. Before posting it Faona had it tested for me it was 518mW with an IR filter.

You can state your opinion in these boards but do NOT misrepresent them as facts.

i still dont buy it.

See what I mean, can't tell the boy anything!

I love this one....concerns burning things......

it is a higher energy photon.

Shorter wavelength.

IR is best, and it's a longer wavelength, absorbed more readily.

Simple physics, 10th grade level.

It depends at what its hitting. besides, ir laser pointers are dangerous. invisible beam, no blink reflex.

Who said ANYTHING about a pointer?? we all know C02 is the king of burning...

not even worth the time....

I already know this.

you have successfully twisted things to suit you once again.

cant twist what's true.
