We offer fiber-coupled laser diodes for the most demanding scientific and industrial applications. Through the implementation of proprietary design, packaging, and fiber coupling technology, these laser diodes offer exceptional reliability and coupling efficiency stability vs temperature variation. Each individual diode undergoes extensive testing procedures before being shipped to guarantee the utmost quality. The module design is tested according to Telcordia GR-468-CORE standard.
Safety and Handling Precautions
Ensure the module is stored or operated in environments where it is not in contact with agressive solvents, acids, bases or corrosive gases
Exceeding absolute maximum ratings even for a short time can cause permanent damage of the module
The module is sensitive to and can be broken by ESD (static electricity), thus all the necessary precauthions should be made (usage of antistatic mat, wrist bracelet, clothes etc.)
Laser diode module should be attached to an appropriate heatsink. Low-noise current source should be used for driving laser diode. For the modules with TEC an appropriate thermal controller should be used.
LD4B, UAB achieves business objectives and customer needs with social responsibility. We do not purchase any parts containing conflict minerals and check that the used components and materials are RoHS and REACH compliant.
