D80 fiber cables for high-power laser delivery are available in different fiber-core diameters from 200 microns to 800 microns (200μm, 300μm, 400μm, 600μm, 800μm). Heat dissipation plays a crucial role in the coupling of high-power. In principle, Lfiber’s D80 fiber cables use step-index double-clad fibers and ferrules of good heat-conducting copper alloys for laser transmission. For better protection, it introduces a sapphire and air gap into the D80 fiber connectors so that the D80 fiber cables can sustain laser power up to hundreds of watts in a single fiber with more than 90% transmission efficiency depending on the fiber core diameters and laser specifications. It’s an excellent choice for fiber-coupled laser systems in wavelength ranges from visible to near infrared (VIS-NIR, typically 400-2400 nm), such as high-power semiconductor lasers, solid-state lasers, and fiber lasers. Areas of application include high power laser transmission, laser welding, laser cutting, and so on. Related Products ↓

D80 Fiber Cables for High-Power Laser Transmission

Lfiber’s D80 fiber cable assemblies for high-power laser transmission are built with step index multimode fiber. The fused silica fiber core is extremely high purity and, as a result, can handle enormous amounts of optical energy. The utilization of epoxy free cantilevered nose design is able to dissipate thermal energy safely without damage materials surrounded. 
 

Compatibility of Lfiber’s D80 Fiber Cables for High-Power Laser

Our D80 fiber cable assemblies for high-power laser are fully compatible with the Ø 4×10 mm industry standard. The outer diameter of the ferrule of d80 laser cable is 4.0 mm, compatible with the D80 laser cables from other brands like Mitsubishi, Miyachi, Han’s Laser, and so on.
