Coherent launches polarization-maintaining optical fiber

Coherent Corp. (NYSE: COHR) announced the launch of its polarization-maintaining optical fiber designed for high-performance fiber laser applications. The product, designated PLMA-EYDF-25P/300-XPH-11FA, targets 1550 nm amplifiers used in long-range LIDAR systems for wind energy and air-traffic sensing markets.

The fiber features a larger mode effective area and enhanced polarization maintaining performance to reduce non-linear effects and enable greater power scalability. The company states the product delivers pointing stability and low 1 µm ASE noise. When combined with its matched passive fiber PLMA-GDF-25/300, the system aims to maximize beam quality and polarization extinction ratio.

"By leveraging our advanced material science, waveguide design, and manufacturing expertise, we have developed a product with a best-in-class doped core material," said Dr. Clemence Jollivet, Senior Director and General Manager of the Fiber Division at Coherent.

The fiber targets applications including materials processing, LIDAR systems, quantum technology, medical laser systems, and scientific research. The product addresses requirements for narrow-linewidth and single-frequency amplifiers in these sectors.

Coherent, founded in 1971, operates in more than 20 countries and provides photonics technology to datacenter, communications, and industrial markets. The company is based in Saxonburg, Pennsylvania.
