초록 ▼

Embodiments of the present invention are sulfur rich glass compositions comprising germanium, gallium and sulfur, which glass compositions have a low energy phonon spectrum and which glass compositions serve as a host for active materials in fabricating light sources such as fiber laser oscillators, light amplifiers, and superluminescent sources. In particular, such a laser oscillator, light amplifier or superluminescent source is comprised of an inventive glass composition which is doped with rare earth ions such as Pr3+or Dy3+for producing light output at wavelengths, among others, substantially at 1.3 um. Further embodiments of the present invention are light sources such as laser oscillators, light amplifiers and superluminescent sources which have emissions substantially at 1.3 um and which are comprised of an inventive glass composition which is doped with Dy3+and Yb3+ions, wherein Dy3+ions are pumped by energy transfer from Yb3+ions. Still further embodiments of the present invention are laser oscillators, light amplifiers and superluminescent sources emitting radiation in a wavelength region substantially at 1.3 um which comprise low phonon energy glasses or crystals doped with Dy3+ .

대표청구항

A laser oscillator comprised of: means for generating pump radiation and applying the pump radiation to a fiber; the fiber being comprised of a sulfur rich Ge-Ga-S host doped with an active material; and the fiber being disposed in a laser cavity.
