This series of LD laser tubes typically require a current-source power supply. When in use, ensure correct alignment of the LD's + and - pins and strictly prevent overcurrent. After use, short-circuit the + and - pins to protect against electrostatic breakdown from environmental static electricity.

1pc 850nm 50mW Single-Mode Fiber Laser Module FFGX-850-SF-FP_50 Optical Pigtail


Semiconductor laser tubes, also known as laser diodes (LD), are currently the most widely used type of laser. This product features TO packaging, commonly adopted by low-power LD lasers. To optimize the output spot quality of LD lasers, all products in this series use an integrated single-mode fiber coupling output. The close-fitting self-focusing lens ensures high-efficiency coupling of the LD laser into single-mode fibers, and the fiber-output LD laser maximally conforms to Gaussian spot intensity distribution. The pigtail end is equipped with common FC/APC or FC/PC fiber connectors, compatible with most fiber flange connectors, fiber collimators, fiber focusing lenses, etc., to facilitate users' subsequent applications.
