U.S. Navy To Test It's Newest Laser Weapon In The Persian Gulf This Summer



U.S. Navy To Test Laser Weapon Aboard Ship In Persian Gulf -- L.A. Times

The Navy plans to install a laser weapon prototype on a ship this summer for at-sea testing in the Persian Gulf.

The technology, called the Laser Weapon System, will be the first of its kind to be deployed, the Navy said.

The idea is that the laser could zap dangerous swarming small boats and flying drones while on the USS Ponce in the Persian Gulf. Its power also can be scaled down, presenting the Navy a non-lethal alternative to ward off threats such as pirates, terrorists and smugglers.

Darpa Wants To Put Lasers On Fighter Jets


DARPA Putting Laser Turrets On Fighter Jets Next Year -- DVice

Our first foray into laser-equipped combat aircraft was the Airborne Laser Testbed, a Boeing 747 with a gigantic chemically-pumped megawatt laser turret in its nose. It was pretty awesome from a conceptual standpoint, but it didn't work very well, and was scrapped last year.

This doesn't mean that the idea of high-powered lasers on aircraft doesn't make a lot of sense, and DARPA is still for ways to make it work. It's working on two at the moment: the High Energy Liquid Laser Area Defense System (HELLADS), and Aero-Adaptive/Aero-Optic Beam Control (ABC).

Lasers: Asia’s Coming “Sci-Fi” Arms Race -- J. Michael Cole, The Diplomat

True to Newton’s Third Law on Motion, weapons development is a constant battle of adaptation with one side unveiling new technology only for the other to respond with countermeasures. Very few platforms in recent years have been as influential or attracted as much publicity as have unmanned aerial vehicles (UAV), which have greatly enhanced surveillance capability while giving their owners the ability to target enemies thousands of miles away at relatively little cost.

Biggest Laser Pulse Fired In Human History Could Power New Kind Of Nuclear Reactor

The future of energy? NIF Director Edward Moses said. 'It is fully operational, and scientists are taking important steps toward the quest for clean fusion energy.'

'Step Towards Clean Energy': Biggest Laser Pulse Fired In Human History Could Power New Kind Of Nuclear Reactor - And Solve Energy Crisis Forever -- Daily Mail

* 'Shaped pulse' of energy generated 500 trillion watts of peak power
* 1,000 times more than the whole United States uses at any given moment
* Array of 192 lasers aims for 'laser fusion' - a 'Holy Grail' of clean energy
* Facility aims to ignite controleld version of reaction found in heart of stars, and in hydrogen bombs

The most energetic laser shot in mankind's history was fired at the stadium-sized National Ignition Facility in California this month.

On July 5, an array of 192 lasers filed a pulse of ultraviolet laser light that deliver generated 500 trillion watts of peak power - 1,000 times more than the whole of the U.S. uses at any given time.

The pulse is a historic moment for the 'fusion' facility, which aims to generate power using a nuclear fusion reaction - similar to what happens in hydrogen bombs.

DARPA Unveils HELLADS, A Portable Laser Weapons System



DARPA Unveils Drone-Slaying War Laser -- Fast Company

A weapon that used to be the size of a passenger jet now fits on the back of a flatbed truck. (Shark mounting apparatus sold separately.)

DARPA is unveiling a portable laser weapons system, HELLADS, which seems like something out of a sci-fi movie. The new laser application, created by General Atomics Aeronautical Systems with a custom power system from Saft Batteries, will help change the way the American military fights future wars. Current military laser systems are bulky contraptions which are mainly the size of a passenger jet, while the proposed DARPA weapon can fit on the back of a flatbed truck. The 150-kilowatt, solid state laser weapon is strong enough to take down drones or other aerial targets; a prototype is expected to be available by the end of 2012.

From New Scientist:

Could astronomers accidentally blind Earth-observing satellites? That seems to be the worry of the US air force, which restricts the use of lasers pointed at the sky to help focus telescopes. But some astronomers warn they will miss key observations under the rules, which have tightened in recent years.

Many of the world's largest observatories, including Lick, Gemini North, Palomar and Keck in the US, shine lasers into the sky to measure atmospheric turbulence, which distorts images.

From The New Scientist:

IT SHOULD be the moment of truth for the Airborne Laser (ABL). In the coming months, the multibillion-dollar laser built into a customised Boeing 747 will try to shoot a ballistic missile as it rises above the clouds.

Don't expect instant reports of success, though. Instead, if all goes to plan, we're likely to hear about a series of incremental improvements.

Laser Cooling May Create "Exotic" States of Matter

An infrared picture shows the change in temperature for laser-cooled gas (blue) and a surrounding metal chamber (red and yellow). After a 30-second pulse from a special type of laser beam, the gas cooled by several degrees compared to its container. Picture courtesy Martin Weitz

From National Geographic:

Laser beams are best known as weapons in science fiction and as heating and cutting tools in science fact. But a new study has flip-flopped conventional physics to show lasers in a whole new light.

In a new technique, Martin Weitz and Ulrich Vogl of the University of Bonn in Germany used a laser to bring the temperature of dense rubidium gas far below the normal point at which the gas becomes a solid.

Underwater Laser Pops In Navy Ops

From The BBC:

US military researchers are developing a method for communication that uses lasers to make sound underwater.

The approach focuses laser light to produce bubbles of steam that pop and create tiny, 220-decibel explosions.

Controlling the rate of these explosions could provide a means of communication or even acoustic imaging.

Lasers Turn Light Into Sound


From Live Science:

A new laser technology has made it possible to turn light into sound.

Developed by scientists at the Naval Research Laboratory, the technology has the potential to expand and improve both Naval and commercial underwater acoustic applications, including undersea communications, navigation and acoustic imaging.

This process is made possible by the compression of laser pulses. Various colors of a laser travel at different speeds in water. These colors can be arranged so that the laser pulse compresses in time as it moves through water, which concentrates the light.

US Lab Debuts Super Laser

A US weapons lab pulled back the curtain on a
super laser with the power to burn as hot as a star


From AFP:

SAN FRANCISCO (AFP) — A US weapons lab on Friday pulled back the curtain on a super laser with the power to burn as hot as a star.

The National Ignition Facility's main purpose is to serve as a tool for gauging the reliability and safety of the US nuclear weapons arsenal but scientists say it could deliver breakthroughs in safe fusion power.

"We have invented the world's largest laser system," actor-turned-governor Arnold Schwarzenegger said during a dedication ceremony attended by thousands including state and national officials.

"We can create the stars right here on earth. And I can see already my friends in Hollywood being very upset that their stuff that they show on the big screen is obsolete. We have the real stuff right here."

NIF is touted as the world's highest-energy laser system. It is located inside the Lawrence Livermore National Laboratory about an hour's drive from San Francisco.
