for application in the spectral range between 200nm and 2300nm

Enormous Analysis and R6D activities have untertaken w.r.t. UV fibers. The purity and the lack of material- and surface defects show significant importance. Meanwhile some reasonable initial design fibers are available.
a) SM or LM fiberswith caw diode laser in violet / UV- A
b) microstructured SM fibers show significant resistance against 100mW input power at 405nm.
Still much remains to be done in UV fiber R&D.
