Article Overview

A diode laser, also known as a laser diode, is a semiconductor device that emits coherent light when an electric current passes through it. It operates using a p-n junction, where electrons and holes combine to release energy as photons, a process known as Light Amplification by Stimulated Emission of Radiation (LASER) . Diode lasers are characterized by their high efficiency in converting electrical energy directly into light energy, making them compact and powerful for various applications . They are commonly used in optical devices, telecommunications, and laser printing .
