The highly reliable JDSU 2495-L4 series diode lasers offer 4 W of laser power from a 105-m fiber into a 0.22 numerical aperture (NA) at 808 nm. It is an ideal source for pumping solid-state materials such as Nd: YAG and Nd: Vanadate. In addition, a 4.5 W version is available at 812 nm for applications with broader wavelength tolerances such as medical and dental. The L4 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 achieved with a distributed architecture using multiple L4 diode lasers 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 L4 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 direct diode applications. |
