Abstract

It is difficult for traditional quartz fiber to meet the requirements of multi-parameters (temperature, pressure, etc.) testing in such harsh environments as high temperature, high pressure, strong corrosion and strong electromagnetic interference. In this paper, an optical fiber growth system based on the CO₂ laser- heated pedestal growth method is designed. The system is composed of optical system, high-precision control system and software system. At the same time, the influence of several factors on the growth of high-quality fibers is analyzed, which includes single-crystal fiber growth speeds, diameters and so on. The system can provide uniform and stable heat source, and has successfully grown sapphire, spinel and other ultra-high temperature optical fibers. Some of which have been applied in engineering practice. In the future, the system can also be used to grow magnesium oxide, zirconia, hafnium oxide and other ultra-high temperature optical fibers. So that it can potentially solve the application problems of optical fibers in the field of ultra-high temperature sensing such as aerospace loading and ultra-high-speed flight.
