FIELD: physics.
SUBSTANCE: fibre-optic guide is obtained by chemical deposition of quartz glass from a mixture of starting gaseous reagents. The optic guide has a core of undoped quartz glass with low content of chlorine in the glass of the core due to considerable excess of oxygen O2 relative to silicon tetrachloride SiCl4 during manufacture.
EFFECT: providing high radiation resistance of an optic guide in the near infrared range by suppressing radiation-induced light absorption.
