High-Power 10 W 976 nm Fiber-Coupled Diode Laser

The JDSU L4t Series fiber-coupled diode laser expands our L4 platform by offering a tighter wavelength range specification of 976 nm for the fiber laser pumping market.
By acurately controlling the wavelength of the epitaxial structure during growth, the L4t is specified at ±3 nm around 976 nm for pumping fiber lasers in this narrow pump absorption bandwidth.
Our 6398-L4t series diode lasers offer 10 W of power from a 105 µm fiber. In addition, the L4t multimode pump modules take advantage of the existing global JDSU manufacturing infrastructure to offer both high brightness and a small footprint with consistent high reliability in a cost-effective solution.
