- wpholmes, on 10/12/2007, -4/+24Interesting, but I wonder how long it will be until a portable version with shark-head mounting capabilities will be developed?
- BloodJunkie, on 10/12/2007, -9/+29It is a safe bet that this will be used to spread democracy in the middle east.
- BloodJunkie, on 10/12/2007, -3/+14There is such a thing as being too hot for too long. Just ask David Hasselhoff.
- SirCharge, on 10/12/2007, -1/+8I just had a "What has the world come to moment" when I realized that the article mentions lasers and the previous poster could only think of CD-Rs and not armies of robots zapping each other Terminator style.
- fugazi, on 10/12/2007, -3/+10Burning cds and dvds at record speeds?
- echosierratwo, on 10/12/2007, -1/+6bet'cha Woz has one.
- antron, on 10/12/2007, -1/+6Pfffpt. My Prescott Pentium can do that easy.
- thebeaz, on 10/12/2007, -2/+7If that laser could pop right through sapphire, I wonder when it would stop? Hope no one was walking their dog outside the test facility.
- dbalaski, on 10/12/2007, -4/+7Cool, er, I mean Hot...
Reading this story makes me want to watch the movie Real Genius again... - Detro, on 10/12/2007, -1/+4I think it would be appropriate to put the label "don't look directly into the beam" on it ;)
- lazerdave, on 10/12/2007, -0/+2I believe the sign you're thinking of is... "Do Not Look Into Laser With Remaining Eye"
- JoeCool1986, on 10/12/2007, -1/+2Or how about we just skip the whole steam engine thing and get that laser hot enough for fusion (which they said is theoretically possible, I think). Now THAT would be pretty dern useful.
- inactive, on 10/12/2007, -1/+2Interesting, maybe it could have applications in fusion.
- mistermoose, on 10/12/2007, -4/+5Burn right through the CD-R.... What is it going to be used for?
- skyhighrockets, on 10/12/2007, -1/+2What is it going to be used for? Burn through ***** ofcourse.
- jbert, on 10/12/2007, -1/+2I have no idea what that article meant. But god it was cool! Where can i get one?
- spartan17, on 10/12/2007, -1/+21 small problem:
lasers are some of the least efficient energy that exists.
So much energy is lost through convection that any practical use of a laser comes down to death ray or blue ray - BloodJunkie, on 10/12/2007, -1/+2dude, micromachines are the BOMB, yo!
- mayhemt, on 10/12/2007, -1/+1Although, the source of such laser is unclear, possibilities are endless, for starters, how about using this laser & heating up water & generating steam & using that steam to drive automobiles? leaving out the gasoline/oil dependence? we are back to steam engines geeeee!
- Mysidia, on 10/12/2007, -1/+1Sounds like a replacement for the microwave.
It's no good for using the steam to drive automobiles, because you need a whole lot of
energy to power the laser; with such electricity available, it would be more efficient to just
power an electric motor instead of a laser. - aveyuen, on 10/12/2007, -2/+2to everyone wondering what's the point:
fs lasers are not used to 'burn CD-Rs', or for 'laser death rays'. They are used for laser micromachining of (usually) semiconductor or optical devices. For example, instead of patterning a device using photolithography to etch 5 um waveguides, they are used to isolate rib-waveguides in Si, SOI, GaAs, InP, etc. Right now they are an incredible research tool, and has applications where micron-scale patterns are needed but the costs of a clean-room and photolith lab are not. Most major universities with some kind of semiconductor physics dept will have a femtosecond laser, in one form or another. - MasterDwarf, on 10/12/2007, -1/+1i love this to hear about this stuff. The pressure alone was incredible. The only thing, I am not sure what happens next. :-/
- WalrusOnIce, on 10/12/2007, -1/+1i'm such an idiot. the only thing that article really told me was that "femtoseconds" was a real word.
i chuckled a bit while reading it, i wont lie. - inactive, on 10/12/2007, -1/+0Do lasers follow Moore's Law ^2?
- WRoach, on 10/12/2007, -2/+1Now that would make a hot shark.
- NewBeatsGroove, on 07/19/2009, -1/+0ooo sign me up i want one of these!!! think how easy it would be to cut wood or tile and even some people you dont like.
- Kosterfield, on 10/12/2007, -2/+0Nobody seems to realize the practical purposes this has. We can disarm the tirggering mechanisms of bombs by burning right through them. Provided we can track right we can shoot straight through the guidance package of any missile. This has potential. It wasn't designed so you could have fun melting CD-Rs. Lasers are the future, they are surgical and deadly.
- haigMeister, on 10/12/2007, -5/+2lol
- jjintheuk, on 10/12/2007, -7/+0Amazing!! Thats hot (the story that is)
Jack
http://www.psp-uk.net - haigMeister, on 10/12/2007, -20/+8Wooo, first comment!!!!
10^18 degrees per second...that's hot. Pity they could only keep it for so short (couple of hundred femtoseconds, with a femtosecond being 10^-15 seconds)... - ericesque, on 10/12/2007, -26/+9honestly bloodJunkie, nobody cares about your political views. WE REALLY DON'T CARE.
