An electrolaser is a type of electroshock weapon which is also a directed-energy weapon. It uses lasers to form an electrically conductive laser-induced plasma channel (LIPC). A fraction of a second later, a powerful electric current is sent down this plasma channel and delivered to the target, thus functioning overall as a large-scale, high energy, long-distance version of the Taser electroshock gun.

Alternating current is sent through a series of step-up transformers, increasing the voltage and decreasing the current. The final voltage may be between 108 and 109 volts.[citation needed] This current is fed into the plasma channel created by the laser beam.

Laser-induced plasma channel

A laser-Induced plasma channel (LIPC) is formed by the following process:

  • A laser emits a laser beam into the air.
  • The laser beam rapidly heats and ionizes surrounding gases to form plasma.
  • The plasma forms an electrically conductive plasma channel.

Because a laser-induced plasma channel relies on ionization, gas must exist between the electrolaser weapon and its target.If a laser-beam is intense enough ,it's electromagnetic field is strong enough to rip electrons off of air molecules creating plasma.Cite error: A <ref> tag is missing the closing </ref> (see the help page). The JIN is intended for safely detonating improvised explosive devices (IEDs). Future designs include weapons mounted on land, air and sea vehicles and as a hand-held infantry version.

Applied Energetics said that the weapons will be able to be used as a non-lethal alternative to current weaponry, but will be able to deliver a high enough voltage jolt to kill.

Applied Energetics / Ionatron say that they are working on an electrolaser system, called LGE (Laser Guided Energy).[1] They are also studying a laser-induced plasma channel (LIPC) as a way to stop people from going through a corridor or passageway.[2]

Phoenix

There was an unconfirmed report that in 1985 the U.S. Navy tested an electrolaser.[citation needed] Its targets were missiles and aircraft. This device was known as the Phoenix project within the Strategic Defense Initiative research program. It was first proved by experiment at long range in 1985, but this report may have referred to an early test of MIRACL, which is or was a high-powered chemical laser.[citation needed]

HSV Technologies

HSV Technologies, formerly of San Diego, California, USA, are designing a non-lethal device which was profiled in the 2002 TIME magazine article “Beyond the Rubber Bullet”. It is an electrolaser using ultraviolet laser beams of 193 nm, and promises to immobilize living targets at a distance without contact. There is plan for an engine-disabling variation for use against the electronic ignitions of cars using a 248 nm laser.[3]

Picatinny Arsenal

Researchers from Picatinny Arsenal have demonstrated that an electric discharge can go through a laser beam. The laser beam is self-focusing due to the high laser intensity of 50 billion Watts, which changes the speed of light in air.[4]

Similar devices

There have been experiments in using a laser beam as path to discharge natural electric charges in the air, causing "laser-triggered lightning".[5][6][7][8][9][10]
