980 nm Pump Laser
Module Unstabilised
100-220 mW
These lasers are designed as pump sources for Erbium-
Doped Fibre Amplifier (EDFA) applications. Proprietary
processes and techniques of coupling the fibre to the laser
allow high output powers which are very stable with both
time and temperature. Devices are available with kink free
output powers from 100 mW to 220 mW.
