Undoubtedly, optical fiber has revolutionized the reform of the telecommunications industry. It has replaced traditionally used copper wires and has become the core part of modern communication. <\/p>\n\n\n\n
With optical fiber, the communication system is a kind of communication system with light as an information carrier. The optical fiber transmits information in the form of electrical signals that are transformed into optical signals. <\/p>\n\n\n\n
Due to the wide application of optical fiber in communication, the rapid development of fiber amplifiers and fiber lasers is seen. Other than this, the optical fiber system is used in medicine, sensing, and other fields. <\/p>\n\n\n\n
When we discuss fiber lasers, high-power fiber lasers always take the limelight. But, many people don\u2019t know why it happens. Also, some people haven\u2019t used high-power fiber lasers yet. <\/p>\n\n\n\n
They have a good beam quality <\/strong><\/p>\n\n\n\n The high-power laser fibers achieve high brightness laser output because their waveguide structure determines that the fiber laser is easy to obtain single transverse mode output. Also, the fiber laser is little affected by external factors, leading to good beam quality. <\/p>\n\n\n\n They are highly efficient <\/strong><\/p>\n\n\n\n By selecting a semiconductor laser, the fiber laser achieves high optical to optical conversion. The semiconductor laser emits a wavelength that matches the absorption characteristics of doped rare earth elements as the pump source. <\/p>\n\n\n\n The energy level structure is simple. So, a few phenomena such as up conversion, excited state absorption, and concentration quenching effectively store energy to achieve high-power operations. <\/p>\n\n\n\n They have a good heat dissipation characteristics <\/strong><\/p>\n\n\n\n As a laser gain medium, the fiber laser uses slender rare earth-doped fiber. Also, the surface area and volume ratio of the fiber laser are very large. Compared to solid-state block lasers, the high-power fiber laser is 1000 times faster. The high-power fiber laser has natural advantages in heat dissipation capacity. <\/p>\n\n\n\n In low and medium power, special cooling of the optical fiber is not needed. But, special cooling plays an important role in high-power fiber lasers. It avoids the decline of beam quality and efficiency caused by thermal effects in solid-state lasers. <\/p>\n\n\n\n
