Science Fiction vs. Science Fact

Lasers are a hallmark of iconic comic series and science fiction novels. While their capabilities and uses vary, in most cases, lasers are highly accurate, work instantaneously and cause minimal collateral damage. But does any of the technology behind these futuristic laser-based systems have a parallel in real-life laser technology? Actually, more than you might think. Read on:

Science Fact:

The color of a laser depends on the wavelength and type. While lasers beams can be made in a visible wavelength, most used in defense applications are not visible.

Science Fact:

Lasers are all about pin point accuracy, not a big boom. For example: A beam can be directed at a five-centimeter spot up to 2 kilometers away. Lasers apply heat to the target causing various failures, such as melting. If the target contains an explosive, the heat effect can cause a big boom.

Science Fact:

There won’t be laser goggles any time soon. Today’s high-power lasers are much too large to hand carry, but can be fielded on a ship, in the battle field, on a plane or even mounted on a ground vehicle.

Science Fact:

True! Lasers can have a virtually unlimited “magazine” and minimal collateral damage.

Science Fact:

Not quite. The laser beam is light and therefore travels at light speed to start working immediately. But once the beam reaches its target, it often takes milliseconds to seconds to destroy the target. Even so, a laser can work its way through targets in a fraction of the time it takes to toast a slice of bread!
