Description

technical field [0001] The invention relates to the technical field of fiber lasers, in particular to a comprehensive teaching and experiment platform for fiber lasers. Background technique [0002] Fiber lasers have many advantages such as long life, compact structure, high efficiency, good heat dissipation, and flexible production, making them gradually replace some carbon dioxide lasers, solid-state lasers, etc., and have been widely used in industrial processing, optical fiber communications, medical equipment, Sensing detection and military defense and many other fields. Especially in the past three years, the sales of industrial fiber lasers have continued to grow. It can be seen that the application of fiber lasers is gradually expanding, so carrying out experiments related to fiber lasers is becoming more and more important to practitioners in the modern laser manufacturing industry. [0003] According to the different doping rare earth ions in the optical fiber, t...

AI Technical Summary

Problems solved by technology

The above-mentioned experimental content is relatively traditional, and is similar to the solid-state laser principle and technology, and the resonant cavity structure only considers the linear cavity. The test of the slope efficiency is the most basic parameter measurement. The experiment of the solid-state laser principle and technology has also been involved. LD The effect of temperature on the output characteristics of fiber lasers is actually the characteristic of LD itself. Self-mode-locking is less effective than nonlinear polarization rotation or saturable absorber mode-locking. It is no longer suitable for the needs of modern ultrafast laser applications, and neither of them involves Amplifier; in addition, for the coupling of optical fibers, etc., a spatial structure is used, which has low efficiency and cannot meet the needs of optical fiber fusion splicing
