Advanced weapon systems using lethal Short-pulse terahertz radiation from high-intensity-laser-produced plasmas

An ongoing project in the Indian Institute of Technology has found the seeds to a possible lethal weapon system for the defense initiatives in India.

The interaction between high-intensity, ultra-short laser pulses and plasmas leads to the emission of coherent, short-pulse radiation at terahertz frequencies. A device is developed that can use the short-pulse radiation at terahertz frequencies to deactivate any electronic systems many miles away and create a virtual shield for any advancing army, navy or air force.

According to the technologists this may be the future missiles and guns. These lethal devices are silent, do not emit any visible spectrum of light and is smokeless and odorless. The short pulse radiation can be used to destroy enemy weapon systems, command and control structures and bases. By varying the frequencies, the human being can be totally unharmed while all their software and hardware can be made useless.

If this kind of weapon systems is developed, the experts predict that there will be no need of physically attacking any country. Their infrastructure can be made useless without physical interference into that country.

A variation of such weapon systems can be targeted from Space Satellites also. Beaming the short-pulse radiation at terahertz from the Satellite can provide an electronic shield for the advancing Army, Airforce and Navy.

The biggest application of this technology can be in the area of anti-terrorism. When militants cross the border into countries like India, Israel, America or Russia, they can be detected and electronically eliminated. Assumption is that when their terror-devices are deactivated, they will become helpless.

A version of the same technology can be also be used to create illusionary effects in the radar systems of the enemy. It cannot create stealth but can create false perception in the radar detection systems.

Application of the technology can be made possible from many miles away. The application can also be used in detecting terrorists in the airport or other public areas.
