Feature 1: Due to the small diameter of the fiber core, high power density is easily formed in the core. Therefore, the fiber laser has high conversion efficiency, low enthalpy, high gain, narrow line width, and is convenient. Efficient implementation of connectivity to current fiber optic communication systems.

Feature 2: Because the fiber has good flexibility, the fiber laser has the characteristics of small size, flexibility, compact structure, high cost performance, and easier system integration.

Feature 3: Compared with traditional solid-state lasers and gas lasers, fiber lasers have higher energy conversion efficiency, compact structure, high reliability, and are suitable for mass production.

Feature 4: Compared with semiconductor lasers, fiber lasers have better monochromaticity, smaller chirps and distortions during modulation, and less coupling loss with optical fibers.
