A team of researchers and engineers at Japan's Osaka University is reporting that they have successfully fired what they are claiming is the world's most powerful laser.A 2 petawatt laser for example, would require more energy to run continuously, than is currently produced by the whole world, thus giant green laser pointer used as weapons to take down aircraft.At sea, where warships offer more room to mount a laser weapon, and powerful gas-turbine engines generate more electricity to give a laser gun.

Researchers in Osaka were able to produce a 2-petawatt laser beam using a device known as the Laser for Fast Ignition Experiment.Leaving aside the fact that you shouldn't be able to see lasers in space, I want to know if there is any technological reason to prefer one laser color to another in space combat, or even to use a laser color not in the visible spectrum.A science-fiction writer gives a brief but useful rant about the misuse of lasers here.

The US military already has a few high powered laser pointer weapons at its disposal, but it’s about to get a hell of a lot more.Researchers test the world's most powerful laser for nuclear weapons experiment at the National Ignition Facility.Scientists in Japan have set the record for the most powerful laser ever fired.In 2009, Directed Energy Systems reached new heights with its scalable building block approach for compact, electric laser weapons when it produced the most powerful light ray created by an electric laser at that time.

On the opposite end of the spectrum, you can build superpowered handheld lasers ranging over 50 Watts. So, what's a Japanese research team to do after firing the world's most powerful laser?NB - the Mid-Infared Advanced Chemical Laser (MIRACL) is a more powerful laser (in lab tests) but this is not designed as a weapon.According to the report of the latest research of Chinese Academy of Sciences, Shanghai Institute of Optics and fine mechanics, strong field Laser Physics National Key Laboratory of developed a 5 petawatt ultrashort ultraintense Laser Pointer system successfully.

Convenience of generating source. Higher-powered Laser Engraver , or those with unusual wavelength properties might be really effective at destroying some things.The invention of the first working laser in 1960 further inspired militaries around the world to research and develop high-energy lasers. Current projects include the use of commercial-off-the-shelf fiber lasers.The warfighter can choose from either missiles or lasers.The Excalibur OPA demonstrated compensation for atmospheric aberration on a sub-millisecond timescale to maximize the laser irradiance at the target.

Osaka's mega-powerful laser is called LFEX, or Laser for Fast Ignition Experiments, and measures more than 300 feet long.Graphite is pretty effective at absorbing lasers, so to protect something like a vehicle against a laser weapon, a dense smokescreen might work. But the momentum doesn't come from the laser itself, rather from the vaporized armor.Would it be possible then that a weaponized laser would be able to 'ignite' dense smoke?

The U.S. Navy’s new laser weapon is up and running in the Persian Gulf, and it is capable of disabling incoming planes or speedboats that could pose a threat to a ship by firing an invisible ray that can target engine systems with incredible precision.The jets will be equipped with a laser pen beam system which locate, track and aim at targets.Help the Air Force define and successfully demonstrate a laser weapon capability for current and next generation aircraft.”
