Polarization Maintaining Passive Double-cladding Fibre
Everfoton's Panda-type Polarization-maintaining Passive Fiber has accurate refractive index distribution and excellent geometrical and birefringent properties. Using special coating with a low refractive index, it achieves high NA (numerical aperture > 0.46) double-cladding
transmission. Meanwhile, the large mode field diameter ensures a good connection with other passive double-cladding fibers, and perfectly matches the active ytterbium-doped polarization-maintaining fiber, which is very helpful to ultrafast laser processing and reducing
high pulse nonlinear effect.
