By coherently combining multiple ultrafast fiber lasers, the power limitation of a single fiber can be overcome. In this kind of coherent combining device, a polarization beam splitter (PBS) is generally used for beam combining (as shown in Figure 1(a)), but this kind of device is more complex, and as the number of combined channels […]
Single-mode fiber (SingleModeFiber): The central glass core is very thin (the core diameter is generally 9 or 10μm), and only one mode of fiber can be transmitted. Single-mode fiber has very small inter-mode dispersion and is suitable for long-distance communication, but it also has material dispersion and waveguide dispersion. In this way, single-mode fiber has […]
