The Lumentum S27 Series of 980 nm pump laser modules uses a number of revolutionary
design steps and the very latest material technologies to signifcantly improve scalability of
the production process. The semicooled 45°C laser diode operation provides for a signifcant
reduction in TEC and overall power consumption. The module meets the stringent
requirements of the telecommunications industry including Telcordia GR-468-CORE for
hermetic 980 nm pump modules.
The S27 Series pump module, which uses fber Bragg grating
stabilization to lock the emission wavelength, provides a noisefree, narrowband spectrum even under changes in temperature,
drive current, and optical feedback. Wavelength selection is
available for applications requiring the highest performance in
spectrum control with the highest power available.
