Definition and Principle of Laser Diode

The working principle of a laser diode involves the process of stimulated emission within a semiconductor material. A laser diode consists of a p-n junction, where forward electrical bias causes electrons and holes to recombine, releasing energy in the form of light. This emitted light is coherent, meaning all the light waves are in phase and of the same frequency, resulting in a highly focused and intense beam.

The structure of the diode allows for efficient light generation, making laser diodes compact and power-efficient. The emitted light is further amplified within an optical cavity, enhancing the intensity of the laser beam. These characteristics make laser diodes widely used in various applications, from telecommunications to medical devices.
