Up to 660 mW Fiber Bragg Grating Stabilized 980 nm Pump Modules (PDF, 0.27 MB)
The JDSU 3000 Series 980 nm pump module uses a planar construction with chip on subcarrier. The high-power laser chip is hermetically sealed in a low-profile, epoxy- and flux-free 14-pin butterfly package and fitted with a thermistor, thermoelectric cooler, and monitor diode. This product uses a polarization maintaining fiber (PMF) pigtail that allows excellent side mode supression ratios (SMSR) over a very wide dynamic range.
The 3000 Series pump module uses PM fiber Bragg grating stabilization to “lock” the emission wavelength. It provides a noise-free narrowband spectrum, even under changes in temperature, drive current, and optical feedback. Wavelength selection is available for applications that require the highest performance in spectrum control with the highest available powers.
