View article: Impact of shaping optical fiber preforms based on grinding and a CO<sub>2</sub> laser on the inner-cladding losses of shaped double-clad fibers
Impact of shaping optical fiber preforms based on grinding and a CO<sub>2</sub> laser on the inner-cladding losses of shaped double-clad fibers Open
We experimentally compared for the first time, two techniques of optical fiber preform shaping based on the mechanical grinding and thermal CO 2 laser processing from the point of the inner-cladding losses. The shaped preforms were fabrica…
