Latest Patents

Christine holds a patent for a "Single-frequency narrow linewidth 1μm fiber laser." This compact, single-mode fiber laser operates with a narrow linewidth of less than 10 kHz and delivers high output power exceeding 2 mW. The laser is constructed using an oxide-based multi-component glass fiber doped with triply ionized rare-earth ytterbium ions. The design incorporates fiber gratings formed in sections of passive silica fiber, which are fused to the active fiber. This multi-component glass allows for higher doping concentrations than standard silica fiber, resulting in increased output power levels in shorter cavities. The formation of gratings in passive silica fiber not only facilitates splicing to other optical components but also reduces noise, thereby improving the linewidth.
