Paper Abstract

Kinetics of sintering of porous glass (further PG) plates of composition 96SiO2 • 3.8 B2O3 • 0.2Na2O (a pier. %) has been explored in these researches. The sintering was carried out under activity of CO2-laser radiation. Wavelength of CO2-laser (λ = 10.6 μm) lies in the range of majority absorption of a silica glass. Definition of making requirements of thin sintered layer with the greatest possible radiuses of curvature was the purpose of researches. Also in researches, the purpose to receive the positive microoptical device (further MOD) from the initial negative MOD has been put. Researches have been made at change of action time (further τ) and a stationary value of a power density of radiation (further q), and also at change q and constant τ.
