Laser-Taser – A Non-Lethal Weapon to disable multiple attackers
~James Dunn

In our wicked world, we have increasing needs for non-lethal weapons. The Laser-Taser provides similar protection as a handgun, but is non-lethal.

A standard Taser at a distance uses two small wires attached to a charged high-voltage capacitor. The wires are shot into the individual and the target completes the circuit for discharging the high voltage and subduing the target.

The problem is that this type of Taser can not be used against more than one person. Once the wires are deployed, an additional assailant can attack without fear of being shocked.

My Proposal:

Lasers can easily be produced with sufficient energies to ionize the air when the light is focused. At one time I calculated the energy needed to ionize air and it is surprisingly small compared to what I had previously estimated. The intensity and duration of contact is so small that it poses little danger to the target person.

Ionized air conducts electricity like a wire.

Two lasers can be built side-by-side and shoot their beams through metal eyelets. The high-voltage generator and capacitor would energize the eyelets.

Aiming and pulling the trigger would turn on the lasers and when the ionized beams hit a conductive surface the energy would discharge through the target.

The problem is that as air ionizes, the ionized air scatters the light making further ionization of the air further from the laser unlikely.

Two methods of accomplishing are available.

The first, the lasers are made powerful enough to shine through an elongated lens that focuses a tight beam at the same time along the entire length to the target. The problem with this is that the lasers have to be comparatively larger then the next option, and the precision required extreme.

The second method allows for realatively low powered lasers shining through a dynamically focusable lens. The lens focus would start at 50 feet and then draw the focus in to within a few inches at a rate that allows for ionization of the air, and quickly enough to allow for a latent ionization long enough to create an entire pathway.

The technology for the second method is readily available.

The same safety precaution as with the standard taser applies; either taser will blind the person if hit in the eyes. Because of the precise characteristics of the lasers, the Laser-Taser will have much greater accuracy. With the standard taser, one shot is all you have available. With the Laser-Taser, if the user misses, they can take another shot immediately; perhaps 1,000 shots per charge.

Continued development could utilize the same technology for transferring energy without wires for short periods of time. Once ionized, only a small amount of current is needed to keep the pathways energized.
