Refraction bends light in an optical fiber laser. The optical fiber cable passes light through an opaque silica glass core that is impure and transparent. Cladding is a layer of silica that has been doped with other materials to reduce its refractiveindex. The core-clad interface will reflect light due to the difference in their refractive index.
Oxygen is often used in the laser cutting process, and sparks flying during the cutting process can easily cause fire. Therefore, there should be no inflammable and explosive materials in the working area, and corresponding protective facilities should be provided at the same time.
