Latest Patents

Zhi Ming Liao holds a patent for a "High power 938 nanometer fiber laser and amplifier." This invention features an optical fiber amplifier that includes a length of silica optical fiber with a core doped with neodymium. The design incorporates a first cladding and a second cladding, each with progressively lower refractive indices. Notably, the first cladding diameter is less than 10 times the diameter of the core. The doping concentration of neodymium is carefully selected to ensure that the small signal absorption for 816 nm light traveling within the core remains below 15 dB/m, surpassing other fiber losses. The amplifier is optically pumped using one laser into the fiber core and another laser into the first cladding.
