HEATING OF OPTICAL ELEMENTS MADE OF HIGH-PURITY QUARTZ GLASSES BY RADIATION FROM POWERFUL FIBER LASER
Annotation
Results of experimental study of heating of the optical elements made of high-purity quartz glass (Russian-made brand KS-4V) with radiation of high-power CW fiber laser are presented. Maximum temperatures of optical element at various power densities of the radiation are measured. The possibility of extrapolating the obtained results to power optics made of quartz glass of other brands produced in Russia and abroad (KU-1, Suprasil 300, and SK-1300) is discussed.
