Soliton fiber laser systems overcome constraints

The thing is that the generation of ultrashort laser beam pulses needs careful monitoring of the light’s dispersion provided by a fiber laser. To be more precise, there is a dependency of phase velocity and frequency, so a real laser beam pulse includes a spread in frequency, it will enlarge as it goes through an...
