Our rare-earth doped fluoride glass fiber excited by blue LD emits multiple colors of fluorescence. This fiber is capable of performing laser oscillation by using optical cavity (resonator).


  • Host medium: waterproof fluoride glass (AlF3-based glass system)

  • Laser oscillation available in various wavelengths. Visible fiber lasers with red, orange, yellow*, green or blue-green emission.
    * Effective yellow emission is rare in solid-state laser materials.

  • Pump source: blue LD

  • Double-clad fibers for multi-mode pumping and producing single-mode lasers. This structure allows multi-mode pumping in the large cladding area while the single-mode signal is generated in the small core region, thereby producing higher-output powers.

  • Simple configuration, highly efficient, and cost-effective laser fiber

  • Emission wavelength ranges of our rare-earth-doped fluoride fibers:


  • RoHS compliant
