We’veknown it was possible for quite some time now — but now there ’s photographic proof . you’re able to use a optical maser balance beam to aim a lightning dash at a mark , with annihilative results .

This photo come via the U.S. Army , which post it last hebdomad but it ’s been pop up everywhere today . The Laser - Induced Plasma Channel ( LIPC ) uses a very short laser burst with a small-scale amount of vigor — but because it ’s so brief , the power muster is tremendous . The output of the “ ocular amplifier ” is 50 billion watts , according to George Fischer , the lead scientist on the Army ’s LIPC task .
As Fischer explains in the Army ’s article / pressure release :
lighter travels more tardily in gas and solid than it does in a vacuum … We typically think of the speed of illumination in each stuff as constant . There is , however , a very small extra intensity - pendent factor to its speeding . In air , this element is positive , so light source slows down by a tiny fraction when the spark is more vivid .
If a laser puts out a pulsation with modest vigor , but the clock time is incredibly tiny , the mogul can be huge . During the continuance of the optical maser pulse , it can be putting out more big businessman than a large urban center needs , but the pulsation only lasts for two - trillionths of a second …
For very herculean and high-pitched intensity optical maser pulse rate , the air can move like a lense , keep the light in a small - diam filum . We utilize an radical - short - beat laser of pocket-size vim to make a laser beam so intense that it focus on itself in air and stay sharpen in a filament .
If a laser ray of light is intense enough , its electro - magnetic force field is strong enough to rend electron off of air molecules , creating plasma . This plasma is located along the path of the laser beam , so we can address it wherever we desire by moving a mirror . Air is draw up of inert molecules and is an insulator … [ But ] the plasma TV channel conducts electricity way better than un - ionized air , so if we gear up up the optical maser so that the filament descend near a gamy voltage informant , the electrical energy will travel down the filament .
