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
