Abstract
The results of experimental studies on the fabrication of preforms of high aperture numerical quartz fiberoptic light guides (with a high fluorine content (up to 7 wt %) and a thickened cladding of quartz glass doped with fluorine) by the nonisothermal plasma of resonance local microwave discharge (PCVD) method are given. It is shown that by using a nonisothermal plasma of resonance local microwave discharge at low pressure, it is possible to achieve high deposition rates of fluorine-doped quartz glass layers (up to 3 μm/min) and the s/a ratio (where s is the preform diameter, a is the core diameter) at the level of 1.3 to 1.4 or higher.
