Do fiber optics use lasers?

Depends on the application. For high speed data transmission, you need to use lasers -- and not just lasers, but lasers with very narrow linewidth in order to minimize dispersion. read more

Another type of fiber laser is the fiber disk laser. In such lasers, the pump is not confined within the cladding of the fiber, but instead pump light is delivered across the core multiple times because the core is coiled on itself like a rope. read more

Fiber versus CO2 laser cutting As a manufacturer of CO 2 laser cutting machines with output power from 2.2 to 6 kW and true fiber laser machines ranging from 2 to 4 kW, Bystronic UK Limited, Coventry, UK, is often asked about the benefits of each type of machine and which is better for specific applications. read more
