DailyDirt: Lasers, Not Attached To Shark Heads…
from the urls-we-dig-up dept
The first laser was made in 1960, and since then, lasers have become increasingly useful — by delivering information through fiber optic cables and in LASIK and other ablative cutting processes. What would we do without lasers? It’s possible that lasers could solve all of our energy needs if inertial confinement fusion ever pans out. We’re still discovering cool things to do with lasers, so check out a few of these links on coherent light sources.
- Laser weapons with kilowatt-scale output are a bit less ambitious than the Strategic Defense Initiative’s megawatt lasers that aimed to shoot down nuclear missiles. However, these less powerful lasers can still take out some rockets or small boats — and may be more cost effective than using conventional missiles. [url]
- Blue lasers were once difficult to make, and now we also have a white laser. The first white laser was recently fired, although white laser light has been previously produced by combining separate monochrome lasers in 2011. Unfortunately, it’ll still take some time before white lasers will be practical for lighting or displays. [url]
- Researchers at Osaka University have created a 2-petawatt laser pulse that lasted just a trillionth of a second. The Laser for Fast Ignition Experiments (LFEX) is over 300 feet long, and powerful lasers like this could be used for fusion energy research (and for weapons, of course). [url]

Laser weapons will have a disadvantaged against traditional heavy metal weapons for a very long time, simply because there is always the problem with providing them with power, and the fact that they need to be ‘attached’ to the area of operation. The failure of the airborne lasers in the Star Wars program was an obvious sign of just how precarious sci-fi tech really is.
Sure, lets weaponize everything because that worked so perfectly in the past.
Cool and awesome approach to life.
Sidenote: every weapon-like thing in these articles are used as a defense against American weapons. Just something to think about…
I look forward seeing a meme (with lasers…) come true. Mayhem!
Laser Guns
So, I guess the “Phased plasma rifle in the 40-watt range” isn’t exactly around the corner? 😀
Cost-effective
“and may be more cost effective than using conventional missiles”
Which is a very good reason to oppose this technology.
