Femtosecond laser micromachining was first demonstrated in 1994, when a femtosecond laser was used to ablate micrometre-sized features on silica and silver surfaces 1,2. In less than ten years the ...
Abstract: A tunable mode-locked ytterbium-doped fiber laser with a tuning range of 55 nm is demonstrated in this paper. Currently, this is the widest tuning range for all-normal dispersion (ANDi) ...
