Patent ID: 8279900

Claim:
A mode-locked fiber laser system, comprising a multicomponent-glass optical fiber doped rare-earth ions of at least one of thulium and holmium and having a length between 0.75 cm and 150 cm, the multicomponent-glass optical fiber being configured as a gain-medium of said fiber laser system, wherein a refractive index of the multicomponent glass of the muticomponent-glass optical fiber is greater than 1.55 at 589 nm, wherein said fiber laser system is configured to be passively mode-locked with the use of a saturable absorber that includes at least one of metallic nano-spheres, metallic nano-wires, carbon nano-tubes, quantum dots, and graphene components, and wherein a pulse-repetition rate of said fiber laser system is between 0.1 GHz and 20 GHz.
