hey i was just wondering does anyone know how to build a laser? or know any sites that have info? any help would be appreciated

What kind [size] are you talking about?

Pointer size? Something that only needs a lazer diode?

Or are you talking the bigger, of the real ruby crystal variety [let's call them 'Industrial' sized]?

Perhaps something even biger?

What do want to do with it?

Point at things? Gun sight? Tease cats, dogs and other small animals?

Make holograms?

Shoot down alien spacecraft? ;-)

Oooo...I want the anti-spacecraft laser.

me too, me too, mount a couple on the roll bars of my jeep and open fire on the hella slow drivers infront of me, not to mention the cocky rice burners

In my library, amongst the many books on how to do just about everything, is the book "How to build a low-cost laser" by Ronald M. Benrey (Hayden Book Co.).

It tells you how to build a low power continuous wave laser. This will do holography and other optical experiments.

It is not the "death ray" laser, it won't even burn tissue paper. To do that you would need to build a pulse laser, those will weld or drill metal.

The book says you can build a low power laser for less than $100.00 US, I imagine the pulse type would cost considerably more.

Ah, but holograms can be made with laser pointers that cost less than the film/plates...

Actualy I was looking for info on the "Death Ray" kind of laser powerful enough to uh well lets see melt steel doors

Cha-ching$$$$$$$

Hard light lasers are very expensive.

id imagine, but ohhhh can you imagine how fun they'd be?

Until it overheated...that's when the real fun begins.

One of my favourite sites is www.futurehorizons.net

The site doesn't have 'death-ray' lasers, exactly, but it's got some pretty cool stuff, and the plans to build them. Now all I need is money to buy the flying saucer...

Check out: "How to Build the Short Frequency Pulsed Laser Pistol". in Popular Electronics, December 2075

I don't think I can wait that long for that issue to come out. I refuse to wait most of my life for a single article, except the January 2050 Popular Science where they will evaluate the claims they made in the Jan 2000 issue about the next 50 years.

I have a 532NM solid state laser, it emmits a fair amount of 1032nm light also the 532 is probibly 500mwatts or so I pop black ballons with 1 teaspoon of talcum powder tolight up the air. this is powerfull enough to burn your skin and blind you. I might part with it for enough $$$'s

532nm? That's such a lovely shade of green. I wonder what strange looks I'd get if I started expressing colors by wavelength, or frequency, or perhaps hexadecimal value? "Hey, the light's 00FF00! Go!" "I love a woman with 505nm eyes..."

LOL I'm going to do that.
