The bulk optical strengths of KU1 and KUVI quartz glasses were determined for pulses of 85 ns duration at the wavelength of 353 nm. The damage thresholds of these materials were the same and amounted to 280 GW cm-2. The optical breakdown thresholds o

The absorption of laser radiation at λ = 193, 248, and 353 nm in KU-1 quartz glass has been measured during the application to the test samples of an electron beam with an energy density up to 1 J/cm2 in a pulse 80 ns long. The induced optical densi

Using experimental samples of type-KI quartz glass processed in a barostatic chamber as an example, it is demonstrated that bubbles can be removed from it virtually completely. An investigation of the quality indices (birefringence, fine-grain inhomo
