Light sources are all around us. From the average incandescent bulb to the screen and flashlight in your phone, many gadgets produce light. LASER stands for Light Amplification by Stimulated Emission of Radiation. Lasers are devices that produce a highly directional beam of light. Flashlights also produce some directionality by focusing light, but they’re nothing like a laser beam!
