Mode Filtered Fiber Amplifier Technology Wins R&D 100 Award

Liekki Corp of Finland, a supplier of highly doped fibres and optical engine modules for fibre laser and amplifier applications, has reportedly licensed and commercialised the same mode-filtered fibre amplifier technology that recently earned Sandia National Labs and the Naval Research Lab an R&D 100 Award. According to Liekki, mode-filtering technology increases the power scaling limits of fibre amplifiers by more than 100 times, enabling the production of multiple kilowatts of output power in a single-mode beam. The company says this advancement will lead to the use of fibre amplifiers in real-world applications such as materials processing, remote sensing, and nonlinear frequency conversion.
