ST2 delivers 200 W of power within 0.15 numerical aperture of 135 µm core fiber leveraging the industry-proven track record of Lumentum ST Series high-brightness pump laser family. It uses a new generation of high-power proprietary chip optimized for reliability at high power. The 200 W laser also supports the “build-your-own” kilowatt (kW) laser market. 

The multimode pump module offers high brightness, small size, and simplified thermal management. The diodes operate as distributed heat sources, allowing air- or water-cooled architectures with predictable high reliability.

The ST Series is a unique solution for the fiber-coupled pump-laser market, offering powerful technical attributes in a cost- effective package.
