Optical fiber and multimode amplifier module for designing pulsed fiber lasers introduced by OFS

NORCROSS, Ga. – OFS Fitel LLC in Norcross, Ga., is introducing the TrueXMF Yb 200/375 optical fiber and TrueXMA multimode amplifier module for pulsed fiber lasers used in industrial surface treatment applications.

The TrueXMF Yb 200/375 optical fiber enables fiber laser manufacturers to build their own pulsed fiber lasers. It has a large multimode core to enable kilowatt average power, high pulse energy amplification with low nonlinearity, and high efficiency and low thermal load.

The TrueXMA multimode amplifier module is an extension of the TrueXMF optical fiber to enable customers to protype their own pulsed fiber laser designs rapidly.

"We've engineered this fiber toward much lower heat loads and also more efficient pump absorption, enabled by the greater index contrast of low-index claddings when compared to a glass-clad approaches," says OFS Product Manager Phil Familletti.

"The design is compatible with traditional high-NA pump combining and has demonstrated preservation of low-divergence and speckle-free signals through long kilowatt-class amplifier lengths," Familletti says.
