Abstract

The dynamics of motion of the channel side walls has been studied in the process of narrow holes formation in glass plates (channel depth to diameter ratio exceeds 4) under the action of pulse-periodical CO₂ laser radiation at 4 (DOT) 10⁴ divided by 1 (DOT) 10⁶ W/cm² intensity. The conditions of relief formation on the channel walls and dependence of relief characteristics on radiation intensity and modulation frequency have been investigated.
