The wavelength of a pump laser diode should be stabilized during operation.
Fiber grating is a simple and good approach for the stabilization of the pump laser diode.
The fiber grating is a simple and efficient approach to stabilize the wavelength of the laser diode. We can offer fiber gratings for 980nm pumping laser diode and 1480nm pumping laser diode. We are also capable of writing the fiber gratings for 850nm laser diode and other wavelength laser diode. The fiber grating forms an external cavity and reflects a very small part of the signal to act as a feedback thus stabilizing the pumping wavelength.
