SINGLE-MODE PUMP LASERS
400 mW Kink-Free Output Power Options
The G&H line of single-mode, cooled 974 and 976 nm pump lasers deliver 400 mW of kink-free fiber-coupled power. The modules are packaged using unique laser-weld packaging technology for high reliability over harsh operating conditions. Improved PER is achieved using advanced fiber pigtail construction techniques.
The hermetically sealed 14-pin butterfly package is available with a fiber Bragg grating and includes thermoelectric cooler, thermistor, monitor photodiode and UniDry™ getter. The fiber Bragg grating precisely locks the center wavelength over extended power and temperature range.
Center wavelengths in the range of 974 nm and 976 nm available with tight wavelength control.
G&H’s pump lasers are designed to meet the requirements outlined in Telcordia GR-468-CORE.
