LASER COMPONENTS has manufactured hard dielectric coatings for optical components in the laser industry since 1986 and is one of the leading producers of these coatings. The fibers are coated using physical vapor deposition (PVD(, which is the most commonly used coating technology in the laser industry. Through the quick layer deposition and flexible capacities coatings can be inexpensively produced with high damage thresholds. In the PVD method, the dielectric coating materials are evaporated inside a vacuum. An electron beam provides the source of energy; alternatively, the energy can come from a crucible heated by a very high current. The molecules set free by this process are deposited in clusters on the fiber tip at an energy rate of approximately 0.1 eV. The layers created have a low dispersion rate and are designed for use with high power levels. The use of these coatings significantly reduces coupling losses. This advantage pays off in applications such as medical technology and material processing. The use of coated fibers is also advantageous when combined with laser diodes. LASER COMPONENTS offers complete fiber assemblies including coatings as well as job coatings on fibers supplied by customers. We can process all types of fibers — from fused silica fibers to sapphire fibers. It is imperative that all materials used, such as, for example, protective buffers, be suitable for high vacuums. For the application are used metal tubes from high-grade steel or teflon tubes. In many applications the quality of the fiber surface is extremely important. LASER COMPONENTS guarantees surface defects <= 5/1 x0.003; C3x0.005.
