Buying Single-crystal Fibers
Unlike most optical fibers made from amorphous materials like glass, single-crystal fibers are made from materials such as sapphire or monocrystalline Nd:YAG. These fibers are used in high-power amplifiers and other specialized applications, benefiting from their superior mechanical and thermal properties.
