A laser diode is a semiconductor device that emits coherent and monochromatic light through a process called stimulated emission.
Laser diodes and traditional light sources have distinct characteristics and applications that make them suitable for different purposes. Laser diode emit coherent and monochromatic light, whereas traditional light sources, such as incandescent or fluorescent bulbs, produce incoherent and broad-spectrum light.
Laser diodes offer several advantages over traditional light sources, including high brightness, efficiency, and the ability to focus light into a narrow beam. This makes Laser Diode ideal for applications that require precision and control, such as laser pointers, barcode scanners, and laser cutting.
Traditional light sources, on the other hand, are more commonly used for general illumination and lighting applications.
