Flat-top beam profile Beam uniformity-reduces hot spots Ultra-low insertion loss Effective brightness conservation Excellent compatibility-compatible with most optical fiber interconnection systems Products can be used at different power levels Homogenized Fiber Everfoton's Homogenized Fiber adopts a special waveguide and structure design, which can be highly compatible with traditional fibers. With special design, the propagation mode in the fiber core can be adjusted to convert the input beam into a uniform flat-top beam profile while maintaining efficient optical propagation and an ultra-low insertion loss. The homogenized fiber can be efficiently integrated with existing optical systems, and used in laser cladding, laser cleaning, laser welding, uniform illumination, spectroscopy, power supply,medical care and other fields.

Perfect fiber geometries and low transmission loss Standard symmetrical square shape with adjustable square core corner radius Homogeneous beam output of the square core Customized shape and size requirements Square Core Fiber Everfoton's Square Core Fiber with special optical spot shaping requirements is developed using the independent patented manufacturing platform.Compared with circular core fibers,the square-core fiber produces output beams that are close to square-shaped. This shape allows for a more uniform treat-ment of output spot energy, making it particularly suitable for high-efficiency welding and heat treatment.

Excellent circular concentricityI ndependently adjustable power between the core and ring regions All-fiber solution to improve system reliability Customized waveguide structure and size Ring Fiber Everfoton's Ring Fiber is designed to meet the high power output requirements of ring lasers and variable beam profile lasers. Different from the single peak Gaussian distribution of traditional lasers, the beam is shaped through the ring fiber to form a Gaussian distribution laser beam in the core area and a ring laser beam around it. The parallel use of the two beams can effectively reduce the spatter of high-power laser welding.
