Fluoride Fibers for Visible Fiber Lasers

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).

Features

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
