Classifications

Definition

Classifications refer to the systematic categorization of different types of fiber lasers based on their design, function, and the materials used in their construction. Understanding classifications helps in identifying the specific attributes and applications of various fiber lasers, enhancing their utility in different fields such as industrial manufacturing, medical procedures, and telecommunications.

5 Must Know Facts For Your Next Test

1. Fiber lasers can be classified based on their operational wavelength, including near-infrared, visible, and ultraviolet lasers, each suited for different applications.
2. The main classifications include continuous wave (CW) and pulsed fiber lasers, with CW lasers providing a steady output and pulsed lasers generating high-intensity bursts of light.
3. Doped fibers are crucial in fiber laser classifications; for instance, ytterbium-doped fibers are popular for high-power applications due to their efficiency.
4. Another classification method is based on the beam delivery system, which can vary from collimated output to fiber-coupled configurations.
5. Each classification impacts performance metrics like efficiency, beam quality, and output power, making it essential to choose the right type for specific applications.
