diodilasers
Diode lasers are semiconductor devices that emit laser light when an electric current passes through them. They are one of the most common types of lasers due to their small size, efficiency, and affordability. The active medium in a diode laser is a p-n junction, typically made from materials like gallium arsenide (GaAs) or indium phosphide (InP). When forward-biased, electrons and holes recombine in this junction, releasing energy in the form of photons. These photons are then amplified within an optical cavity, leading to the emission of coherent laser light.
The wavelength of the emitted light is determined by the semiconductor material used and its composition. Diode
Applications for diode lasers are extensive. They are found in everyday items such as barcode scanners, CD
