ST3 delivers 335 W of power within 0.15 numerical aperture of 200 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 335 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 diode operates as distributed heat sources, allowing 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.
