Product Description

Boxoptronics 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 optical fiber has good consistency, better suppresses 1um parasitic ASE, has high light-to-light conversion efficiency, and has good stability under high-power operation conditions.
