Laser Diodes, Laser Modules

A laser diode, or LD, is a type of semiconductor diode that is designed to emit light when a current is applied to it. Laser diodes are used in a wide range of applications, including data storage, optical communication, and medical technology. Laser diodes are commonly packaged in a small, compact form factor, and are available in a variety of wavelengths, power levels, and beam shapes to suit different applications. A laser module is a complete laser system that includes a laser diode, as well as additional components such as collimators, lenses, and mounting hardware. Laser modules are commonly used in applications where it is necessary to use a laser in a compact and portable form factor, or where the laser must be easily integrated into a larger system.
