Product Description
Erbium-ytterbium co-doped fiber is mainly used in high-power telecommunications CATV optical amplifiers, lidars, and eye-safe lasers. We provide Er/YB co-doped fiber with good beam quality and high conversion efficiency, which can facilitate the high-power output at 1.5μm. Based on the unique doping system, the absorption coefficient and gain spectrum can be adjusted based on the customer needs.
| Features High precision geometric dimension control High efficiency and power output Low splice loss with SM28e fiber | Applications Materials Processing, scientific research and medical High power fiber amplifier LIDAR |
