High Power Fiber Coupled Diode Laser with Customizable Collimators Available
As new energy and industrial laser processing industries boom worldwide, high-power fiber coupled diode lasers have become core light sources for plastic welding, battery busbar welding and fiber laser pumping. Our FC976DL1200 976nm 1200W fiber coupled diode laser stands out for stable CW high-power output, high electro-optic conversion efficiency and reliable long-term operation, widely favored by system integrators from Europe, Russia, Southeast Asia and India.
However, raw divergent beam output from fiber tips restricts processing precision and consistency for kilowatt-level laser systems. That is why we provide customizable laser collimators perfectly matched with our 976nm high-power diode laser modules to solve beam divergence issues fundamentally.

How Our Laser Collimators Optimize Beam Quality
The collimator adopts one or multiple positive focal length lenses to converge divergent laser beams. The divergent light emitted from the fiber end will be reshaped into uniform large-diameter light with ultra-low divergence angle and consistent optical axis. It effectively reduces thermal loss, eliminates local over-burning and significantly improves processing precision and batch consistency for welding and cutting production lines.
Core Advantages of Custom Water-Cooled Fiber Laser Collimators
- Fitted with universal QBH/QB interfaces for seamless assembly with 1200W fiber coupled diode lasers. Built-in integrated water cooling system continuously takes away heat absorbed by lenses, effectively restraining thermal lens deformation under long-hour high-power CW operation.
Quick Installation with Standard Interface
