Fiber-coupled laser
All CNI laser products can be supplied with multi-mode or single-mode fiber coupling options in various core diameters. Customers can select the appropriate laser for fiber coupling based on its specific performance characteristics—such as power, stability, noise levels, and size—and we’ll do our best to meet your requirements.
Standard coupling methods allow you to choose between free-space output and fiber coupling.
