High Absorption Large Mode Field Erbium-ytterbium Co-doped Fiber

BoxOptronics High Absorption Large Mode Field Erbium-ytterbium Co-doped Fiber has a unique core low NA design, which can achieve high beam quality output without reducing the pump conversion efficiency. The high cladding NA ensures high pump coupling efficiency, and the large core diameter design ensures a large mode field area and a short fiber length, thereby greatly reducing the threshold of nonlinear effects. The fiber has good consistency, better suppression of 1um parasitic ASE, high light-to-light conversion efficiency, and good stability under high-power operation.
