Frequently Asked Questions

A larger core (14 µm) with low numerical aperture (0.09) spreads the same optical power over a larger mode area, which lowers the peak intensity in the fiber and reduces nonlinear effects like self-phase modulation — important for high-pulse-energy amplification.

The fiber is characterized for both 980 nm (15±2 dB/m absorption) and 1480 nm (12±3 dB/m absorption) pumping, giving flexibility in pump source choice.

Yes — versions with mode field diameter up to 25 µm are available on request for applications needing even lower nonlinearity.
