    Study Notes

    Fiber Lasers

    • The active gain medium in a fiber laser is the rare earth doped fiber core.

    Advantages of Fiber Lasers

    • Fiber lasers have the advantage of being more reliable, efficient, and compact compared to other types of lasers.

    Fiber Nonlinearities

    • Fiber nonlinearities such as stimulated Raman scattering or four-wave mixing can provide spectral broadening, wavelength conversion, and pulse compression for a fiber laser.

    Industrial Applications

    • Fiber lasers are important for laser cutting, welding, and folding of metals and polymers due to their high precision, speed, and quality of processing.

    Notable Advantage

    • A notable advantage of fiber lasers is their high power density without thermal degradation, which allows for high-speed processing of materials.
