摘要：
A study was made of the influence of temperature and optical power level on the magnitude of induced absorption in fiber-optic waveguides made of pure quartz glass. It was found that coupling additional bleaching radiation into a waveguide at a power level of approximately 10** minus **6 w decreased its induced absorption by several orders of magnitude. Previously unknown quartz-glass induced-absorption bands were discovered and their optical and thermal bleaching investigated.
