General Description
The EM250 single mode, cooled 1060 nm pump laser delivers up to 400mW of fiber-coupled power. The module is packaged using the unique, patent pending technology Uniline™ for permanent fiber alignment. Uniline™ provides superior end-of-life optical and electrical performance, achieved by maintaining a highly stable, all-axis alignment lock between the laser chip and the tip of the single-mode fiber.
The hermetically sealed 14 pin butterfly package includes a thermoelectric cooler, thermistor, monitor photodiode and UniDry™ getter. EM4’s Uniline™ family of pump lasers are qualified to meet the requirements outlined in Telcordia GR-468-CORE.
