Abstract
Fiber rods of 10% doped Yb:YLF were fabricated with the micro-pulling-down technique and characterized. The crystal axis was oriented along the rod length, allowing polarized emission with the largest cross section available in the direction. Laser experiments showed that these fiber samples perform similarly to crystals grown by the standard Czochralski method. Intrinsic slope efficiency of was measured in both cases, with small comparable intracavity losses, proving the good quality of the fiber material.
