High-Power 8.5 W 9xx nm Fiber-Coupled Diode Laser (PDF, 0.22 MB)
JDSU's highly reliable series diode laser offers 8.5 W of laser power from a 100 μm fiber into a 0.2 numerical aperture (NA). The L3 package is a redesign of the existing fiber-coupled L2 package, incorporating a telecommunications design in a commercial product.
The L3 multimode pump module is based on single-emitter diode lasers and allows for a radical departure from standard bar-based pumping architectures.Hundreds of Watts of highly reliable pump power can be easily achieved with a distributed architecture using multiple L3 and a multimode fiber coupler or fiber bundle. In a
distributed architecture, "cascading" failure modes are avoided, and ensemble statistics can be used to predict pump assembly lifetimes. The L3 multimode pump module eases thermal management by distributing the diode lasers (heat sources), allowing for a simple air- or water-cooled architecture in laser pumps and directdiode applications.
