Xia Hong, Lumentum PLM, gives an overview of Lumentum's new pump laser series
2 x 800 mW Fiber Bragg Grating Stabilized 980 nm Pump Modules
The Lumentum D2 Series is dual-chip 980 nm pump module with each emitter independently controlled. It uses a number of revolutionary design steps to provide high optical power density within a compact space. The D2 Series pump module incorporates the Lumentum high-reliability, high-efficiency 980 nm laser diode in a cooled fiber Bragg grating-stabilized 14-pin low-profile butterfly design. The module meets the stringent requirements of the telecommunications industry, including Telcordia GR-468-CORE for hermetic 980 nm pump modules.
The D2 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 performance in spectrum control with the highest power.
