How do you get the laser?
Laser (Light Amplification by Simulated Emission of Radiation), is generated by a light emitting laser medium (lasing material) and optics to manage the light emitted from the… lasing material. The lasing material can be charged electrically or optically so that the atoms or molecules in the lasing material have high energy states. Light is emitted when a high energy atom or molecule changes to a lower energy state. As the emitted light hits other high-energy atoms, more light is emitted. The generated light will have the same wavelength (color), phase angle and direction as the incoming light. As a result, light is amplified in the charged lasing material. Arranging optics, such as two parallel mirrors, to bounce the generated light back into the lasing material, can create more light that moves in the same direction. (MORE)
