Frequently Asked Questions

The single-mode signal-input end (typically 8/80 µm) carries the input signal, while the large-mode-area end (typically 40/400 µm) is used for signal output and pump input in cladding-pumped amplifier schemes.

Thanks to a high ytterbium concentration and a short taper length, amplifiers built on this fiber can reach nonlinear-effect thresholds of up to 0.5 MW — among the highest reported for this fiber class.

Yes — it uses a PANDA structure with F-doped second cladding, suitable for coherent and narrow-linewidth amplifier architectures.

Yes, the tapered fiber length is configurable from 2 to 3 m on request; other parameters are available on request.
