1940nm Infrared Fiber Coupled Laser System

1940nm Laser Module with Fiber Coupling  All series CNI laser modules can be fiber coupled with different core diameter MM fiber or SM fiber. You have  to refer to the detailed specs of each laser modules (such as power, stability, noise, size, etc) to decide which one is suitable for your application. We would like to do the coupling job for you.
