Description
A Laser Diode is a semiconductor device similar to a light-emitting diode (LED). It uses p-n junction to emit coherent light in which all the waves are at the same frequency and phase.. And since a p-n junction is used to produce laser light, this device is named as a laser diode.
The sunlight or incandescent bulbs have waves with several wavelengths but they are not in phase with each other. But these diodes generate a thin laser light beam where all the light signals contain the same wavelengths & they move together. So, laser rays are extremely bright which targets an extremely small spot.
