The Lumentum S29 Series 980 nm pump laser modules use a number of revolutionary design steps and the very latest material technologies to significantly improve production process scalability. The semicooled 45°C laser diode operation significantly reduces TEC and overall power consumption. The module meets the stringent telecommunications industry requirements, including Telcordia GR-468-CORE for hermetic 980 nm pump modules.

The S29 Series pump module, which uses fiber Bragg grating stabilization to lock the emission wavelength, provides a noise-free, narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications requiring the highest spectrum control performance with the highest power available.
