10 W 915/940/975 nm Fiber-Coupled Diode Laser

Lumentum L4-series diode lasers offer up to 10 W of power from a 105 μm fiber. The L4 is a revolutionary platform based on a long history of existing fiber-coupled L2 and L3 packages, incorporating a highly reliable design into a scalable commercial product.

L4 multimode pump modules offer high brightness, a small footprint, and simplified thermal management by distributing the diodes (heat sources), allowing the use of either air- or water-cooled architectures with predictable high reliability.

Lumentum leverages existing manufacturing facilities around the world to offer a cost-effective solution with all the necessary and ideal attributes for the laser pump market.
