Lasers explained – put order into the world of Photon [video]

Learn how laser works by watching this interesting video from Minute Physics. Laser is only light, but that light is organized in a well focused beam with more and more photons in a given area. They have the same orientation and polarization and thus having more such organized photons will help you create the ultimate Light Sword.

Laser is the acronym for “light amplification by stimulated emission of radiation” and it saw the light in 1957 when Charles Hard Townes and Arthur Leonard Schawlow, from Bell Labs, starter to work very hard on infrared radiation, but instead they concentrated on visible light. Good they did that!
