Table Top USP Lasers Slice, Dice, and So Much More
UltravioletLED writes "A company in Petaluma, California has developed highly programmable desktop lasers. The same devices used in hospitals could also be used to turn any metal surface black by simply changing the software. From the article: 'The technology once filled a large room at DARPA until Raydiance scientists made it into a compact, tabletop unit. Schuler (The CEO) said he hopes it will replace just about any cutting device you can think of, from a big metal saw to a precise surgical blade ... Now that it's a little bigger than a breadbox, researchers want to use them to kill tumors, identify friend or foe during combat, and even remove tattoos.' Femtosecond lasers for eye surgery have been around for years now, but these new lasers are far smaller and promise to have much greater versatility."
Now I can play SkyTag!

Dude, that's not the correct order to do things in, or you're being highly presumptuous.
Until I see some freaking sharks with freaking lasers on their heads!
so how long before it can be reduced to the size of a TV remote with a range of a metre or so?
And will I have to make my own?
If I use it in anger does it become a red one?
Did Han shoot first or not?
If my call is important, why am I talking to a recording?
Shouldn't that be 'giant laser' in you butt?
Do they come with sharks? ...

All from the comforts of home!
Until they manage to create suitable tabletop sharks upon which to mount these frickin lasers, I ain't impressed....

Yeah, I turned a whole bunch of stuff black when I last played with lasers. It pays to stay out of the way of the little red beam, it transpires.
The dosing device goes together with laser therapy apparatus comprising only low-energy semiconductor and gas lasers. Its control mode is set with regard to the functional condition of the patient's body, the disease dynamics and stage.
It's time to realise that Abble's products are the biggest abomination these days. Just say NO to the dumb iAbble way!!
I wonder what this'll do to the "right to bear arms" debates.
Does anyone know where I can go to learn to build my own desktop lasers? I have found Sam's laser FAQ before, but surely there are other sources out there.
Was I the only one who read Table Top USB Lasers Slice, Dice, and So Much More? Man that would've been cool. :)

This would make for an awesome USB device, though I suspect it might need a teeny tiny bit of external power.
I wonder how it would work with regards to:
- cutting velveeta cheese
- deterring the neighbors cat from pissing in my garden
- deterring my neighbor from pissing in my garden
- frying wood tics
- boiling water
- removing warts
- engraving my initials on the water tower, from across town
- lighting a joint

"It is possible to synthesize excited bromide in an argon matrix! Yes, it's an excimer, frozen in its excited state ... As soon as we apply a field, we couple to a state that is radiatively coupled to the ground state. I figure we can extract at least 10 to the 21st photons per cubic centimeter which will give one kilojoule per cubic centimeter at 600 nanometers, or, one megajoule per liter."
"Looks at the facts: Very high power. Portable. Limited firing time. Unlimited range. All you'd need is a big spinning mirror and you could vaporize a human target from space.

I was just talking with my friend about desktop fabrication and we came upon the topic of using metals rather than plastics.
I proposed that it may be possible to have two canisters of particle-ized metals which could perhaps be alloyed together on a very small scale. This could be done using a standard 3D fabrication gantry system and some kind of micro-sized welding nozzle head thingy.
Seeing a desktop cutting laser made me consider that this might work very well as the welding method - rather than electric arc-welding or gas: how could you even miniaturize those?

Did Han shoot first or not?
Of course Han shot first, but after a few years he had everyone convinced that it was self defence, because that's what scoundrels do.
I used to do waterjet cutting, and we had looked into laser cutters as well, but many materials are toxic when burned.. so we stuck with water. There are applications, where a laser is better. Wood is not practical with a waterjet because it absorbs water and the wood warps. Metals are problematic, but can be cut with laser, although much easier to add sand to a waterjet stream and cut it with water. I know that there were also cutters being developed using high pressure air. The waterjet machine I ran was made by Flow International, really an awesome machine. I kinda miss that job.

Man that would go perfect with this.

Sweet! Table-top laser dice! Shit, that's awesome!
er..wait. They are 20-sided, right?
Compared to normal lens, apo plan lenses have a long working distance. They are used in inspection microscopy because around the focus distance, you won't crash into the sample you are looking at. If I'm not mistaken, the red colour coding of the lens used here indicates it's a near infrared lens.
Microscope lenses are often used with lasers to focus light into a tiny spot (say, into a fiber). The lens threading on the apo plan lens is also compatible with Thorlabs SM1 threadings, which make those ideal for... burning things at a distance using off-the-shelf bits and bobs!
bundaegi is good for you
"It can cut metal, heal burns and kill cancer tumors -- all without damaging heat.
"All you need is one of his ultrashort pulse, or USP, lasers, he said. To change the function, just change the software".
Hmmmm. So this laser can do different things. One moment, it's a deadly weapon. The next, it's a harmless cosmetic aid.
And which of these things it does will be determined by... software? Written and maintained by whom? With what sort of utterly foolproof user interface?
Can you say "Therac-25"?
I am sure that there are many other solipsists out there.
From most other posts this appears to be old news.From my standpoint,its sad because I could not afford one.I wish to use it in conjunction with a copy machine to reproduce fine musical instruments and parts.(my own designs,of course,well,maybe some beloved to me too.) ,they will cum" relevant here?
It's wonderful they have this,but disappointing when its still out of reach.Kinda like all the jetpacks,birdman suits,robots,computer clusters,super displays and other really practical cool shite that never makes it to the common man.
What's wrong?This shite is cooler than the consumer shite we have!Where is the adage"if you build it
I guess it's kinda like the bubbletop cars of the 50's and all the other "space age" glitz they waved in the faces of common man then too.Just some hype,an advertisement,empty promises....sigh.
Well they can keep their crap to themselves and don't bring it out unless they mean it.BAH!

My husband owns a laser-engraving business (that's his URL that I have listed - my own website is pretty boring). He has just a little 45 watt one, but it cuts fine through wood, acrylic, plastic... even leather, though the smell of scorched flesh is pretty nasty. He can't cut metal, but there are plenty of ways he can mark it. Including one that bonds a black coating onto it.
And, I might add, these lasers are expensive. Making a smaller version of a higher power laser than he owns means that it's certainly out of the price range of all but the richest households. (Heck, I can't see where it hurts to say it - his 45 watt laser with a 24 by 18 bed weighs in at around fifteen grand. Higher power lasers, like those that can cut metal, are more in the six digit range, IIRC.)
