Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align. First developed in the 1960s to amplify microwaves, modern lasers technology can ramp up light rays in just about any part of the electromagnetic spectrum, with the exception of gamma waves. The word stands for Light Amplification by Stimulated Emission of Radiation – which in a technical sense explains how lasers operate. Though to be more precise, lasers today don't amplify the light – they oscillate the waves within the beam to arrange them in a neat and tidy order. Swapping out the amplification…
