Antiresonant hollow core fibers are significantly more complex to fabricate than solid core fiber, in part due to the need to maintain the uniformity of the complex microstructure along the entire fiber and the lack of techniques available ...
Ultrafast watt-level fiber-feedback multipassoptical parametric oscillator [0.03%]
