They are designed with excellent properties such as high birefringence and great polarization maintenance. Our Er-doped and Er/Yb PM fibers are offered with high QCE values minimizing the fiber length and thus reducing nonlinear effects. The invention belongs to the technical field of optics and laser photoelectrons, and particularly disclosesAn ytterbium-doped polarization maintaining fiber is provided, which comprises a fiber core, an inner cladding, an outer cladding and a stress layer. The measured critical bending radius, R c, defined as the radius at which the loss is equal to 3 dB. In this Letter, we demonstrated experimentally an efficient approach to directly amplify cylindrical-vector beams with axially symmetric polarization and doughnut-shaped intensity profile in a picosecond MOPA system based on a double-clad ytterbium-doped tapered fiber.
