Ydf optical fiber polarization-maintaining optical fiber

Coherent Large Mode Area (LMA) polarization-maintaining Yb-doped fibers are designed for laser and amplifier systems requiring linearly polarized output. With a 25 µm core diameter and a 250 µm cladding diameter, the VIII version ensures high pump absorption and robust beam quality. Excellent geometric and birefringence properties can effectively reduce nonlinear effects in the optical system. As a gain fiber, it has high conversion efficiency and excellent beam. Based on hybrid wavelength pumping and tapered Yb-doped fibers (T-YDFs), a 650 W all-fiber single-frequency polarization-maintaining fiber amplifier was demonstrated experimentally at 1030 nm.
