Description

Having a external cavity forming FBG wavelength locker will precisely locking the pump laser diode by feeding back a small portion of the laser signal that significantly improving the pump laser power and wavelength output accuracy and reliability. It eliminate the pump laser spectral mode hopping and reduce the power intensity fluctuation due to the temperature and pump driving current changing therefore greatly improve the pump laser performance.

The FBG wavelength locker can be in the form of single or twin depends on different pump locking Requirement.
