Xia Hong, Lumentum PLM, gives an overview of Lumentum's new pump laser series
250 mW Uncooled 3-pin 980 nm Pump Modules
The Lumentum H11 Series uncooled 3-pin low-profile planar package pump module uses revolutionary chip and package design to significantly reduce the 980 nm pump size and power consumption. The module meets the stringent requirements of the telecommunications industry, including Telcordia GR-468-CORE for hermetic 980 nm pump modules.
The H11 pump module employs Lumentum’s unique 980 nm distributed feedback laser chip which integrates a high-power laser and grating into a single high-reliability laser die. It provides a noise-free, narrow-band spectrum even under temperature, drive current, and optical feedback changes.
