FIELD: chemical and electrical engineering. SUBSTANCE: novel method for manufacture of blanks for activated fiber light guides based on quartz glass included steps of feeding working gas mixture made up by SiCl4+O2+Ar and vapors of matter containing alloying component from one end of bearing pipe, initiating stationary SHF discharge from opposite end of pipe, and precipitating reaction products on internal surfaces of this pipe. Working gas mixture and vapors of matter containing different alloying components were alternately admitted into pipe, separately for each alloying component. EFFECT: higher quality.
