Product Description

The Polarization maintaining erbium ytterbium co-doped fiber is mainly used in 1.5μm polarization-maintaining optical amplifiers, laser radars, and eye-safe laser products.It has high birefringence and excellent polarization-maintaining properties. The fiber has a high doping concentration and energy transfer efficiency, which can reduce the required pump power and fiber length, thereby reducing the impact of nonlinear effects. At the same time, the fiber shows high efficiency and excellent beam quality, low fusion loss, and strong bending resistance.
