300 mW High-Reliability 980 nm Pump Modules for Aerospace and Test and Measurement Applications
The Lumentum 5050 Series 980 nm pump laser module features low thermal impedance, a single-mode polarization-maintaining fiber output with a fiber Bragg grating (FBG) to stabilize the wavelength, and a hermetically-sealed 14-pin butterfly package.
The laser chip is based on GaAs/AlGaAs/InGaAs Fabry Perot structure. A low-reflectivity Bragg grating is integrated in a polarization maintaining fiber pigtail to provide wavelength stability. The pump modules are to be supplied in a butterfly package with an integral rear facet monitor photodiode.
