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 higher conversion efficiency, lower threshold, higher gain, narrow line width, and convenient Efficiently realize the connection with the current optical fiber communication system.
Feature 2: Because the fiber has good flexibility, the fiber laser has the characteristics of small and flexible, 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, more compact structure, high reliability, and are suitable for mass production.
Feature 4: Compared with semiconductor lasers, fiber lasers have better monochromaticity, can produce less chirp and distortion during modulation, and have less coupling loss with the fiber.
