9XX Cooled Single Mode Pump Lasers AC1405
A 14-pin, TE-cooled, fiber-coupled, PM, single-mode pump laser module that operates at 974 or 976 nm with an output power up to 400 mW.
Full Product Description- Center wavelength:
- P=Pₒₚ, 974 nm, 976 nm
- Operating power:
- Kink free power = Max: 400 mW
Product description
A fiber Bragg grating (FBG) precisely locks the center wavelength over extended power and temperature ranges.
The modules are packaged using unique laser-weld packaging technology for high reliability over harsh operating conditions and are available with a fiber Bragg rating, thermoelectric cooler, thermistor, monitor photodiode, and UniDry™ getter. G&H’s pump lasers are designed to meet the requirements outlined in Telcordia GR-468-CORE.
Key features
- Internal cooler and thermistor
- Fiber Bragg Grating (FBG)
- Telcordia GR-468-CORE compliant
