Laser diodes and modules, which emit coherent light through stimulated emission, often require specific accessories to optimize their performance or integrate them into larger systems. Accessories for laser diodes and modules may include heat sinks for thermal management, optical components for beam shaping and collimation, mounting brackets or fixtures for secure installation, and safety equipment such as laser goggles. These accessories ensure proper operation, safety, and longevity of laser systems in diverse applications including telecommunications, medical devices, industrial processing, and scientific research.
