Congrats!

Re-draw time!

well, yes, a Free Electron Laser works by using a circulating stream of electrons as the lasing medium, but it doesn't output a beam of electrons, which is what the article states. Most likely yet another case of journalist who didn't listen to the what the scientists were saying and just wrote...

ummm, is this a laser or a particle accelerator?

i have heard of CO₂ lasers having that effect when focused tightly. i imagine anything with enough wattage in a sufficiently thin beam would do it.

I am in as well.

for burning through something that smokes, would you not be better off in pulses? burning constant-duty means after burning starts, you waste most of your energy reflecting off smoke.

yeah, no joke. I think we did that in biology once. For a human to be able to breath enough water for successful gas-exchange at the rate our lungs provide breathing air, we'd need to have gills with something like 6-9 times the surface area provided by our lungs. I wonder if the laser...

No True Scottsman would doubt the veracity of our quackery!!

Jesus, can you imagine what the tuneup cost would be? those stupid triple-electrode, platinum plated spark plugs that self-weld to the engine block after a few hours of running. add to that the fact that the coil-pack and the plug boot are the same unit.... i can see it now, ford starts...

they are stamped lm340

So, i salvaged 7 LM340 regulators out of some junk audio equipment at work today. Are they any use for making laser drivers? I am not extremely well-versed in the details of electronic components, so comparing datasheets with the 317 tells me nothing useful. can the 340 be used in the same...

yeah, i figured actually cutting the wood would be a bit far-fetched, but is scoring it really that far out there? also, what product are you referring to on the Aixiz page? i assume an enclosure of some kind, but i don't see that in their store.

So, i have never purchased a laser-pointer, outside of the <5mW Walgreen Special, but i have gone through many phases of running helter-skelter around the internet ooh-ing, aah-ing, and drooling at various .1-1w diode lasers, but not wanting to commit $50-$500 on a laser from a company i know...
