Did you know that we all use lasers everyday? It’s true. DVD players feature lasers. So do the barcode scanners at the grocery store. Of course, any cat owner probably has a laser pointer because they love to torture their pets.
So the question I want answered is, why aren’t we using laser guns? Shouldn’t we have them by now? What’s the hold up, am I right?
Lasers have indeed been a long time in coming. A laser is a device that emits light (electromagnetic radiation) through a process of optical amplification based on the stimulated emission of photons. The term laser originated as an acronym for Light Amplification by Stimulated Emission of Radiation. The emitted laser light is notable for its high degree of spatial and temporal coherence, unattainable using other technologies.
It was way back in 1917 when Albert Einstein first established the theoretic foundations for the laser in his paper On the Quantum Theory of Radiation. In 1928, Rudolf Ladenburg confirmed the existences of the phenomena of stimulated emission and negative absorption. Over a decade later, Valentin Fabrikant predicted the use of stimulated emission to amplify short waves. Another ten years went by before Willis Lamb and R. C. Retherford found apparent stimulated emission in hydrogen spectra and effected the first demonstration of stimulated emission. Finally, in 1957, Charles Townes and Arthur Schawlow, then at Bell Labs, began a serious study of the infrared laser.
After all this time, laser weapons are still in the experimental stage. The general idea of laser-beam weaponry is to hit a target with a train of brief pulses of light. The rapid evaporation and expansion of the surface causes shockwaves that damage the target.
People who know me all agree that I am generally peace loving. So why do I want to develop such a terrifying weapon? Because if we plan to travel into the future or explore deep space, we are likely to encounter technologically superior cultures. We need to be prepared to fight a battle on their terms. The only way we can do that is with lasers.
As you can see, I am looking to create peace, not make war.
That is all.
