Polarization Maintaining Passive Fiber

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.

Precise control of geometric parameters
Excellent birefringence
Matching active polarization-maintaining ytterbium-doped fiber with good fusion compatibility
